Question

If m∠4 = (3x)° and m∠8 = (x + 40)°, what is the measure of ∠4?
∠4 and ∠8 are vertical.
A.
20˚
B.
60˚
C.
40˚
D.
120˚
please help!

Answer 1

if the angles are equal that means \[3x=x+40\]solve for \(x\)

Answer 2

when you find \(x\) multiply it by \(4\) to get your answer, or add \(40\) to it, the answers must be the same

Answer 3

Satellite has it!

Answer 4

did you solve \[3x=x+40\]yet?

Answer 5

@satellite73 Couldn't they look at it such as ;
\[3x = 1x + 40\]

Answer 6

If so that may help them solve it.

Answer 7

Or make it simple. :P

Answer 8

yes, the invisible 1 i hear so much about

Answer 9

Satellite it makes it soo much easier. :-)
