What must the angles in a triangle add up to?

Answer 1

The angles in a triangle must add up to 180 degrees.

Answer 2

If a triangle has a 32° angle and a 67° angle, what is the measurement of the third angle?(1 point)

Answer 3

The third angle would be 180 - 32 - 67 = 81 degrees.

Answer 4

If two angles of a triangle add up to 110° , what is the measure of the third angle?(1 point)

Answer 5

The third angle would be 180 - 110 = 70 degrees.

Answer 6

Find x in the figure.

Answer 7

To find an angle in a triangle, you subtract the sum of the other two angles from 180 degrees. So to find x, you subtract the sum of 35 and 40 from 180.

180 - 35 - 40 = 105

So, x is 105 degrees.

Answer 8

70+50+c+d=180

Answer 9

First, add 70 and 50 together which gives you 120. Then, subtract 120 from 180, which gives you 60. Therefore, the sum of angles c and d is 60 degrees.
