It depends on what your measuring and the measure of the other given angles. "X" is also known as the missing angle.
ex. In triangle ABC, the measure of angle A is 40 and the measure of angle B is 80 find the missing angle.
answer- Angle C would be 60 because a triangle's angles add up to 180 degrees.

The measure of the second angle of a triangle is 21 degrees more then the measure of the first angle the measure of the third angle is 15 degrees less than the measure of the first angle. each is?
Let the measure of the first angle be x⁰. So that the second angle would be (x + 21)⁰, and the third one would be (x - 15)⁰.Since the sum of angle measures in a triangle is 180⁰ we have:x + x + 21 + x - 15 = 1803x = 174x = 58Thus, the first angle is 58⁰, the second angle is 79⁰, and the third angle is 43⁰.
Find the measure of an angle that is 30 degrees more than its supplement?
Suppose the measure of the angle is x then its supplement is 180 - x x = 180 - x + 30 = 210 - x 2x = 210 => x = 105 degrees (supplementary angle = 75)
Two angles of a triangle measure 15 and 85 what is the measure for the third angle?
Assuming the third angle is x... 180 = 15 +85 + x 180 = 100 +x 80 = x The third angle is 80 degrees
In a triangle the measure of the middle angle is triple the measure of the smallest angle and the measure of the largest angle is 55 degrees greater then the measure of the smalest angle Find measures?
x + (3x) + (x + 55) = 1805x + 55 = 1805x = 125x = 25 . . . 3x = 75 . . . x+55 = 80Check . . . 25 + 75 + 80 = 180 yay!
What is the measure of an angle whose measure is nine times its supplement?
Supplement of an angle measure x* be y*=(180-x*). Or x+y=180* for the problem x=9y => x+y = 9y+y=10y=180 => y=18* and x =172*
If the measure of an angle is three times the measure of its supplement then find the measure of the angle?
x is the angle you're looking for and 3x is the angle that when added to x must total 180 degrees. Therefore the angle is 45degrees (x + 3x = 180)
The measure of an angle is fourteen times the measure of a complementary angle. What is the measure of each angle?
Let's denote the measure of the angle as x degrees. The complementary angle would then be 90 - x degrees. According to the given information, we have the equation x = 14(90 - x). Solving this equation, we find x = 70 degrees and the complementary angle is 20 degrees.
The measure of the second angle of a triangle is 21 degrees more then the measure of the first angle the measure of the third angle is 15 degrees less than the measure of the first angle. each is?
Let the measure of the first angle be x⁰. So that the second angle would be (x + 21)⁰, and the third one would be (x - 15)⁰.Since the sum of angle measures in a triangle is 180⁰ we have:x + x + 21 + x - 15 = 1803x = 174x = 58Thus, the first angle is 58⁰, the second angle is 79⁰, and the third angle is 43⁰.
What is the measure of an angle that is nine times its supplement?
The supplement of an angle x is equal to 180 - x. The measure of an angle that is nine times its supplement can be written as: x = 9(180 - x) You can then solve for the measure of the angle x: x = 1620 - 9x 10x = 1620 x = 162 Therefore, that angle which is nine times its supplement is itself 162 degrees.
The measure of an angle's supplement is 44 less than the measure of the angle?
Suppose the angle is x degrees. Then its supplement is 180 - x So 180 - x = x - 44 224 = 2x so x = 112 degrees.
What is the measure of x if the measure of angle abd is represented by 2x the measure of angle dbc is represented by 5x and the measure of angle abc is 91 degrees?
The answer is 13. x=13 13*5+13*2=91 Thank you.
If the measure is four times the measure of the complement what is the measure of the angle?
Suppose the angle is x then its complement is 90-x So 4*(90-x) = x or 360 - 4x = x so that 360 = 5x => x = 72 degrees
What is 11 degrees from a angle?
x - 11 degrees, where x is the measure of the angle you started with.
The measure of an angle if its measure is 50 more than its complement?
Suppose the angle is x. Then its complement is 90-x x - 50 = 90 - x or 2x = 140 so that x =70.
Find the measure of an angle that is 30 degrees more than its supplement?
Suppose the measure of the angle is x then its supplement is 180 - x x = 180 - x + 30 = 210 - x 2x = 210 => x = 105 degrees (supplementary angle = 75)
Two angles of a triangle measure 15 and 85 what is the measure for the third angle?
Assuming the third angle is x... 180 = 15 +85 + x 180 = 100 +x 80 = x The third angle is 80 degrees
Two angles are complementary If the measure of one angle is 20 more than the measure of the second angle what is the number of degrees in the measure of the smaller angle?
first you have to change this into equation by "translating" it into math. so let x= the first angle 90-x ( because complementary means they add up to 90) = the second angle x= (90-x) + 20 x+x = 90-x+20+x 2x = 90-20 2x = 70 x = 35 the smaller angle = 35 degrees
