Question

Can u help me pls
I don”t know what to do

Answer 1

Explanation:

Do you know SOHCAHTOA

Sin = opposite/hypotenuse

Cosine = adjacent/hypotenuse

Tangent = opposite/adjacent

#1

We have to find cos(x) = adjacent/hypotenuse

`cos(x) = adj/hyp\\=(24)/(26) = (12)/(13)`

#2:

We are given an angle of 30 degrees and an opposite side of 15

We need to find the adjacent side, so we can use Tangent

`tan(30) = (15)/(adj)`

`adj = (15)/(tan(30)) = 25.98 = 26`

#3

We are given an angle and an opposite side and we have to solve for hypotenuse.

We can use sin

`sin(43) = (16)/(x) \\x = (16)/(sin(43)) = 23.46 = 23.5`

#4:

We are given two sides, we have to find the angle. We are given an opposite side and an adjacent side, so we can use arctangent (
`tan^-1(x)`, but not 1/tan(x))

`tan(x) = (36)/(19) \\arctan(36/19) = x\\x = 62.1759`

#5

We are given an opposite side and the hypotenuse, we can use sin

`sin(x) = (19)/(28)\\x = arcsin(19/28) = 42.73 = 43`
