Question

50 POINTS QUICK PLEASE,

How do i solve

Answer 1

m ∡20 = 44°

Explanation:

Given:

l ║ m

m ∡3 = 136°

m ∡14 = 113°

To find :

m ∡20 = ?

`\textsf{Solution:}`

We have:

m ∡3 ≅ m ∡17 =136° Since corresponding angle are congruent.

Again:

m ∡20 + m ∡17 =180° Since sum of linear pair is 180°

Substituting value

m ∡20 + 136° = 180°

Subtracting both side by 136°, we get

m ∡20 = 180° - 136°

m ∡20 = 44°

Therefore, m ∡20 = 44°
