Question

Find the value of x.
x(x+4)
148⁰

Answer 1

Explanation:

The angle on top of x(x+4) is equal to 148.

The angle at x(x+4) = 180 -148 = 32

`x(x + 4) = 32 \\ {x}^(2) + 4x = 32 \\ {x}^(2) + 4x - 32 = 0 \\ (x - 4)(x + 8) = 0`

x-4=0

x=4

x+8=0

x=-8

Answer 2

the answer is 148 the reason is two angle interception
