You will at 7 to both sides and then divide 2 on both sides to find x. :)
2x-7=3
+7=+7
—————
2x = 10
— —-
2 2
X = 5

1 and 5 are corresponding angles, so both have the same measure:
m 1 = m 5
m 1 = 65º
Answer: option D. 65º.
I hope this helps. =)
Divide 12 by all of the ingredients then multiply them by 18
Pythagorean theorem is formula we would use:
1.)
c^2=a^2+b^2
c^2=10^2+24^2
c^2=100+576
c^2=676
c= √676
c=26 in
2.)
c^2=7^2+14^2
c^2=49+196
c^2=245
c= √245
c~15.65 cm
