Step-by-step explanation:

perform multiplication and division first, working from left to right, before doing addition and subtraction.

First solve parenthesis: (also solve 4^2)

4^2 + (10 - 2 × 3) ÷ 4

16 + (10 - 6) ÷ 4

16 + 4 ÷ 4

16 + 1

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
