Question 1-20
Determine mzi.
기
1
33°
83°

Answer 1

`m < 1 = 116 \: degrees`

Explanation:

To find m < 1 we have to first acknowledge that a triangle measures 180°. You should also note that a straight line also measures 180°. Therefore the third unknown angle in the triangle would be:

`180 - (33 + 83 = 116) \\ 180 - 116 = 64\\ unknown \: angle \: is \: 64° \\`

Since the unknown angle and m < 1 form a straight line then that means that they add together to make 180°. Hence

`m < 1 = 180 - 64 \\ m < 1 = 116°`
