Step-by-step explanation:
b.
The sum of two opposite interior angles equals one exterior angle
111°=60°+‹G
‹G=111°-60°=51°
c.
We use the same property above
3x+4x+5=68°
7x=68-5
7x=63
x=63/7=9
‹D=4(9)+5
‹D=41°
What are the solutions to the equation x2 = 64?
A.
8 and –8
B.
8 only
C.
32 and –32
D.
32 only
