Question

Solve for the missing measure. Round decimals to the nearest tenth.

b =

Answer 1

\[\tan(50)=\frac{b}{4}\iff b=4\tan(50)\] and a calculator

Answer 2

40?

Answer 3

that i not what i get, no

Answer 4

90+40+50= 180

Answer 5

idk

Answer 6

angle A = 180 - 50 -90 = 40

4/sin40 = bsin50
bsin40 = 4sin50
bsin40 = 3.064177772
b = 3.064177772 / sin 40
b = 4.77

like this maybe? ???.???

Answer 7

*4/sin40 = b/sin50

Answer 8

why would i use sin

Answer 9

cuz you have angle A, side A, and Angle B i guess?

by using the sine law where:

A/sinA = B/sinB = C/sinC
