Question

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

Answer 1

`100^o`

Explanation:

The sum of the measures of the three angles of the triangle is `180^o`.

So,

`35^o +45^o + z = 180^o`

`80^o + z = 180^o`

`z=180^o - 80^o = 100^o`
