a).Find the height of the mountain.
(round to the nearest hundredth)

Answer 1

tan18=x/3950

Answer 2

x=3950(tan18)
x=1283.43

Answer 3

how can i find angle C

Answer 4

like the other side of angle C and B

Answer 5

Angle B = 180-31

Answer 6

why is it 180? -31

Answer 7

angle c = 180-(59+90+18)

Answer 8

the measurement of horizontal line is always 180 degrees

Answer 9

angle C= 72 degrees

Answer 10

but 180-1657=13

Answer 11

i mean 180-167=13
