Answer:
4. 21
5.120
Step-by-step explanation:
(the answer for #4
I added 5x+15 and 3x-3
and got
8x+12
and because we needed to find the value of x, l did this
8x+12=180
because interior consecutive angles equal 180
and I got 21
(answer for 5)
I then plugged 21 into 5x+15 because angle 1 is equal to it
5(21)+15
I got 120
B.40 if angles are corresponding that means they add up to be 90 degrees and 50 plus 40 equals 90
49/-7 and -21/3 are the only two equivalent to -7
