Answer:

It's C because we are adding a number on the x but here we skip 5 so it's 6, and on y we add 4 up but since we skipped 5 we add 8 and we get 24. 6, 24. You may say "but SpiritBear, 17 plus eight is 25" and that is true, but if you notice the lowest dot actually starts on 5, not 4 making C right.

Hope this helped and wasn't too confusing

I thin the best answer among the following choices base on the data you have given and the formulas, to be honest I didn't really understand the instructions but in your diagram, this is just my suggestion but no an answer, the value of #1 2nd option from the left of the first line and the #2 is the last choice from the first line. I hope this would help

Approximate the unknown side x in the diagram. <br> A. 3.356<br> B. 5.222<br> C. 3.064<br> D. 4.737

Marianna [84]

Answer:

The answer to your question is x = 3.356 cm

Step-by-step explanation:

This is a right triangle so we can use the Trigonometric functions to solve this problem.

Data

Ф = 40°

Adjacent side = 4 cm

Opposite side = x

Process

1.- We must know the lenght of the opposite side so we must use the tangent to solve it.

tangent Ф = $\frac{Opposite side}{Adjacent side}$

2.- Solve it for Opposite side

Opposite side = tanФ x Adjacent side

Opposite side = tan 40° x 4

Opposite side = 0.839 x 4

Opposite side = 3.356

Opposite side = x = 3.356 cm
