Question

Given the following diagram, find the missing measure.

?

m_2 = 50", m 3 = 100°,m _4 =
30
o 50
O 100
o 150

Answer 1

answer 180⁰

Step by Step explanation:

All angles in a triangle add up to 180.

1) add up the angles that are already given to you.

50⁰ +100⁰=150⁰.

2)Then take that away from 180⁰. which leaves you with 30⁰

Answer 2

m∡4 = 150°

Explanation:

m∡1 = 30° because there are 180° in a Δ

m∡4 = 150° because angles 1 and 4 form a linear pair and must add up to 180°
