The missing value is x than tan 13 / 24
tan x = 0.5
x = tan-1 0.5
x = 26.60
Answer = 26.60
Solve: QR = 16 ; PR = 2 ; PQ = 8, tan __?__ = 8 / 16

26.2

Step-by-step explanation:

PQ/QR = 8/16 = 0.5

tan(26.6) = 0.5

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

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
