You're given a table of x values and an equation. To solve, plug in the values for x.
First box: y=2(-3)-1=-7
Second box: y=2(-2)-1=-5.
See if you can solve the third one.
I hope this helps you
COS28=15/17
Answer:
x=20
Step-by-step explanation:
We know that a line is 180 degrees, and the base of the cemi-circle is a line. So, we would have:
x+7x+x=180
9x=180
x=20
Hope this helps!!
Problem 9
By definition,

Answer: 502.4 m
Problem 10
From geometry, the angle opposite x is 27°.
By definition,

Answer: 263.3 yd
To answer this question, you first need to know what SohCahToa is.
S- opposite over hypotenuse
C- adjacent over hypotenuse
T- opposite over adjacent
In this situation, they have made it easier for you as they have given you the quotient of the opposite and adjacent sides (3.4) . Now in order to find an angle, you take the inverse of your expression. So instead of just Tan, you would plug in Tan^-1. So plug it in:
Tan^-1 (3.4)
Answer is 73.6 degrees.
