Question

two adjacent angles are add up to 140 degrees one is 4 times the other find the angles​

Answer 1

Step-by-step explanation:

let the angle be x and y

x=4y

x+y=140

4y+y=140

5y=140

y=28

x=4y=28×4=112°

Answer 2

Answer :

• One angle is 28° and the other is 112°

___________________________

Given :

• Sum of two adjacent angles = 140°

• One angle is 4 times the other angle

To Find :

• Angles

Solution :

• Let the unknown angle be x , then other angle will be 4x .

• Now , According to the question :

$\implies \sf x\:+\:4x \:=\: 140°$

$\implies \sf 5x \:=\: 140°$

$\implies \sf x \:=\: \dfrac{140}{5}$

$\implies \sf x \:=\: 28°$

• One angle is 28°

• Other is 4x = 4(28) = 112° .
