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.
What is the supplement of a 60 degree angle?
180 - 60 = 120 degrees.
What is the degrees of each angle of an equilateral triangle?
Each angle is 60 degrees. (180/3)
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.
