Question

The value of x from the following figure, is
Х
3
BO
4​

Answer 1

Answer:

y+y+40° =180°

y=70°

x=40° +y

(exterior angle)

⇒x=110°

∠x=180° −2(30° )=120°

∠ACB=180=−120° =60°

x+65+60=180°

x=55°

Answer 2

Answer:

5

Step-by-step explanation:

hypotenuse=side+side(of right angle triangle)

AC^2=AB^2+BC^2("^" means square )

X^2=3^2+4^2

X^2 =9+16

X^2=25

X=√25

X=5

Therefore, the value of x is 5.
