a triangle has 180º
so 180-90-25= 65
Since an equilateral triangle is also equiangular, all the angles have to be congruent. Because all the angles must also add up to 180 degrees, each angle is 60 degrees.
It will have two equal base angles of 70 degrees.
The two angles are complementary, seeing as they add up to equal 90 degrees.
it depends on the angle. Right angles always have 90 degrees. You can use a protractor to measure the angle
the other is 4 degrees. supplementary angles add to 180 degrees
Each one is 40 degrees.

180 degrees
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
The two angles are complementary, seeing as they add up to equal 90 degrees.
it depends on the angle. Right angles always have 90 degrees. You can use a protractor to measure the angle
Supplementary angles are two angles that measure up to 180 degrees. EXAMPLE: If the an angle measures 70 degrees, to find the missing angle, you subtract 70 from 180 because supplementary angles equal 180 degrees. Your answer (in this case 110) is the answer for the measure of the missing angle.
If that is the angles of a triangle then the 3rd angle is 110 degrees
The angle is 160 degrees and it's supplement is 20 degrees.
A protractor is nused to measure angles in degrees.
the other is 4 degrees. supplementary angles add to 180 degrees
