Question

the question is on the attachment given below pls help me solve

Answer 1

Answer:

The angles are 77°, 55° and 48° respectively

Step-by-step explanation:

(3x-7)° + 55° + (x+20)° = 180° (Linear Pair)

(3x-7)° + (x+20)° = 125°

3x-7°+x+20° = 125°

4x+13° = 125°

4x = 112°

x = 28°

So, putting the value of 'x' in the given equations

(3x-7)°

= [(3×28)-7]

= 77°

(x+20)°

= (28+20)°

= 48°

So, to verify the answer

we know that the sum of all angles given is 180° (Linear Pair)

77°+55°+48° = 180°

180° = 180°

So, the answer is correct

Hope it helps!!
