Answer:
MV = 160 (and %50 sure) X = 27
Step-by-step explanation:
To find MV we just have to subtract the two lengths of the perimeter that we do know, minus the total perimeter, and find the difference. (using that its, 605-160-285 = 160) with that knowledge, we can say two things. MV = 160, and <V = <T by the two side lengths being congruent. With that, we can say that X + X +X+99 = 180, and then just find X, 27+27+27+99=180.

Answer:
19
Step-by-step explanation:
If t = 7
Then 5 + 2t would be equal to
5 + (2*7)
5 + 14

Angle (8x)⁰ and angle (2x+60)⁰ are congruent angles as corresponding angles.
So,
8x = 2x+60
8x - 2x =60
6x = 60
x=10
Answer C. 10
Answer:
cos 90°
Step-by-step explanation:
(cos 60°)(cos 30°) − (sin 60°)(sin 30°)
= cos ( 60° + 30°)
= cos 90°
