If James earned 90% on a test and got 36 points, how many points did he lose from the total possible points? helppp PLEASE I'll mark the brainlest

4

Step-by-step explanation:

90 percent is 9/10 of total possible

x = total possible points

x * 9/10 = 36

x = 36 * (10/9) = 4 * 10 = 40

40 - 36 = 4

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
