Let x equal the first angle.
let 4x= the second angle
let 3x+10
x+4x+3x+10=180 The sum of the interior angle measures of a triangle is 180 degrees.
8x+10=180 combine like terms
8x=170 addition(subtraction) property of equality
x=21.25 degrees
The third angle is (128 degrees) minus (the second angle).
It is 90-28 = 62 degrees
It is a right angle triangle and the 3rd angle will measure 30 degrees
It will be 62 degrees because 90-28 = 62
If you mean an equilateral triangle then the 3rd angle is 60 degrees
In a triangle the measure of the first angle is four times the measure of the second angle. The measure of the third angle is 18 degrees more than the second angle. What is the measure of the first angle? 68 43 17 95
If its a right angle triangle then the second acute angle is 62 degrees
100.
The third angle is (128 degrees) minus (the second angle).
54 degrees
It is 90-28 = 62 degrees
It is a right angle triangle and the 3rd angle will measure 30 degrees
It will be 62 degrees because 90-28 = 62
50 degrees if its a triangle
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.
If you mean an equilateral triangle then the 3rd angle is 60 degrees
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
