9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.
10) y = 14 x = √147 or 12.12435565
11) x = 4.8
12) x = 4.2
13) x = 9.3
14) pq: 13.2
qr : 17.6
angle p: 53º
15) angle c: 54.3º
angle a: 35.7º
16) h = 21040
v = 1841
step-by-step explanation:
10) 7/sin(30) = 14 = y
7^2 + b^2 = 14^2
49 + b^2 = 196
b^2 = 196 - 49
√b^2 = √147
x = √147
11) cos(70) x 14 = 4.788282007
x = 4.8
12) tan(25) x 9 = 4.196768923
x = 4.2
13) sin(31) x 18 = 9.270685348
x = 9.3
14) pq: sin(37) x 22 = 13.23993051
pq: 13.2
qr: cos(37) x 22 = 17.56998122
qr : 17.6
angle p: 180 - (37 + 90) = 53º
15) cos-1(7/12) = 54.31466529
angle c: 54.3º
angle a: 180 - (90 + 54.31466529) = 35.68533471
angle a: 35.7º
16) 4 x 5280 = 21120
cos(5) x 21120
h = 21039.63202
h = 21040
sin(5) x 21120
v = 1840.729287
v = 1841
