Question

<17 and <18 are vertical angles. m <17=(5x+3)(degrees) and m<18=(3x+23)(degrees) find the measure of <18

a. 13 degrees
b. 44.3 degrees
c. 53 degrees
d. 33 degrees.

i just need the answer please i have to go!

Answer 1

angle 17 and angle 18 are equal to each other for vertical angles are equal :P
so 5x + 3 = 3x + 23
can you combine like terms?

Answer 2

yes 5x and 3x?

Answer 3

no o.o
5x + 3 = 3x + 23
- 3 - 3
5x = 3x + 20
-3x -3x
2x = 20
2x/2 = 20/2
x = 11

Answer 4

is it 53??
