Nora loves to play the Bridge Builders video game, where players gain and lose points by
building safe and unsafe bridges. In Level 1, Nora earned 16 points because her bridge
passed inspection. Then, she lost 25 points because part of her bridge collapsed!
i really dont know
step-by-step explanation:
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
