Question

(i) in the adjoining figure, angles are in
linear pair. What is the value of x?
(4x + 60)° (x + 20)°




plzzzz solve and give the answer and show how to solve it !!!!!!​

Answer 1

Step-by-step explanation:

(4x+60)(x+20)=180

4x^2+80x+60x+1200=180

4x^2+140x=180-1200

x^2+140x=-1020

x^2×140x+1020=0

Now by splitting.

Answer 2

solution: Find x=?

therefore x +20+4x+60=180

4x+x+20+60=180

5x+80=180

5x=180-80

5x=100

x=100/5

x=20
