Question

If two angles of a triangle are a linear pair and their measures are
3x + 10 and 2x – 40, find the angles​

Answer 1

Step-by-step explanation:

3x +10+2x-40= 180. (linear pair)

5x-30=180

5x=180/30

x=6/5

Answer 2

$\sf \Large Solution!!$

3x + 10° + 2x - 40° = 180° (Linear Pair)

5x - 30° = 180°

5x = 180° + 30°

5x = 210°

x = 42°

1st angle => 3x + 10 => 3(42°) + 10° => 136°

2nd angle => 2x - 40° => 2(42°)-40° => 44°

Verification.

136° + 44° = 180°

180° = 180°

LHS = RHS

Hence, verified.
