Answer 2

Answer:

Hey !

Step-by-step explanation:

3.

In this all are making linear pair

so sum is 180 degrees

(x+3)+(x+20)+(x+7)=180

3x+30=180

3x=150

x=150/3

x=50

4.

Here also a+b+90 = 180 (linear pair )

given

a/b=2/3

therefore

a=2b/3

Put this value

2b/3+b+90=180

take lcm

(2b+3b+270)=540

5b+270=540

5b=270

b=54

Now a+b=90

a+54=90

a=36

now a and c make linear pair

therefore

36+c=180

c=144

HOPE IT HELPS :) :)

if u liked my explanation drop a thanks :) :)
