Answer:
Side AB would need to be congruent to side DE, side BC would need to be congruent to side EF, and side CA would need to be congruent to side FD.
Step-by-step explanation:
Answer: C) complementary angle and D) right angle
Step-by-step explanation:
A is wrong because supplementary angles add up to 180 and this shows a right angle not a straight line
B is wrong because this a right angle not a straight angle
C is correct because complementary angles are two angles that add up to 90 degrees. angle EFH is split into EFG and GFH which adds up to 90 degrees.
D is correct because you can see the right angle symbol for angle EFH

Answer:
6
Step-by-step explanation:
7x + 3(-x + 6) = 42
use distributive property
7x + -3x + 18 = 42
positive + negative = negative
7x - 3x + 18 = 42
combine like terms
4x + 18 = 42
subtract 18 from both sides
4x + 18 - 18 = 42 - 18
18 is canceled out on the left side
4x + 0 = 24
4x = 24
divide both sides by 4
4x ÷ 4 = 24 ÷ 4
1x = 6
x = 6
