Question

if Y /X= 5 and Z/X=4, then the value of x is( refer to the picture above) step by step explanation.
(a) 8°
(b) 18°
(c) 12°
(d) 15°
​

Answer 1

Answer:

The answer is (b) 18°

Step-by-step explanation:

From the given conditions we get,

Y=5X and Z=4X

We know that,

Angle(X)+Angle(Y)+Angle(Z) =180°

X+5X+4X=180°

10X = 180°

Therefore:

X = 18°
