Question

Find the value of x​

Answer 1

okaY!

See 3x+8+5x+4=180(Linear Pair)

8x+12=180

180-12=8x

168=8x

c=168/8

Got,X=21

Answer 2

$\huge \bold \red{heya}$

We know that the given pair of angles will form a linear pair.

▶3x+8+5x+4=180°

▶8x+12=180

▶8x=180-12

▶8x=168

▶x=21°

Therefore,

The first angle=3x+8=3(21)+8=71°

Second angle=5x+4=5(21)+4=109°
