What else can I help you with?
A triangle has a 30 degrees angle and a right angle What is the measure of the third angle?
Angle A + Angle B + Angle C = 180 degrees. 30+90+C=180 120+C=180 C=60 degrees.
Does a right angle measure 60 90or 180 degrees?
90
What is the third angle on a triangle if you have 60 degrees and 60 degrees?
The last angle would have to be 60 degrees as well. Since there are 180 degrees in a triangle, 60+60=120 and 180-120=60, it has to be 60 degrees.
How many degrees are there in each exterior angle of an equilateral triangle A 30 degrees B 60 degrees C 90 degrees D 120 degrees?
an interior angle + and exterior = 180 Angle A: 180-30=150 Angle B: 180-60=120 Angle C: 180-90=90 Angle D: 180-120=60 SO WHATS THE ANSWER!!!?????
In a right-angled triangle besides the right - angle one of the angles measures 30 degrees what does the other angle measures?
60 degrees. There are 180 degrees in a triangle.
What is the supplement of a 60degree angle?
Supplementary angle add to 180 degrees. So the supplement to a 60 deg angle is 180 - 60 = 120 degrees.
A triangle has one angle of 80 degrees and another of 60 degrees how manydegrees must there be in the third angle?
There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
Can an equilateral have a right angle?
No, an equilateral triangle can't have a right angle, because an equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees.
How do you calculate the missing angle of an equilateral?
In an equilateral triangle, all three angles are equal, and each angle measures 60 degrees. To calculate the missing angle, you can use the formula for the sum of angles in a triangle, which is 180 degrees. Since the other two angles are both 60 degrees, you can subtract their sum from 180: 180 - (60 + 60) = 60 degrees. Thus, the missing angle is also 60 degrees.
If one side of a triangle is 30 degrees what degree does the third angle need to be to make it a right angle?
sum of all angles in a triangle is always 180. So 30 degrees, plus the right angle (90) = 120. 180-120 = 60
Can an equilateral triangle have a right angle?
No, an equilateral triangle can't have a right angle, because an equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees.
What is the supplement of a 60 degree angle?
180 - 60 = 120 degrees.
