Question

The measures of two angles of a triangle are 35° and 45°. What is the measure of the third angle of the triangle

ج

Answer 1

100°

Explanation:

triangles always add up to 180 degrees

First add 35 and 45

35+ 45 = 80

Then subtract 80 from 180

180-80 =100

Answer 2

The third angle is 100 degrees.

Explanation:

The three angles of a triangle add to 180 degrees.

Lets call the third angle x

x+35+45 = 180

Combine like terms

x +80 = 180

Subtract 80 from each side

x+80-80 = 180 - 80

x = 100

The third angle is 100 degrees.
