<span>3(x + 5) = 3 · x + 3 · 5</span>
Answer:
The second answer
Step-by-step explanation:
P'Q'R' is simply rotating PQR 90 degrees, it does not change the angle that it makes
5x+19=6x+1 because of parallel postulate.
x=18
Answer:
First Option: cos(x)
Step-by-step explanation:
What is given is csc(x) = 14/10
The graph lies in the first quadrant since 0 < x < pi/2
Create a triangle:
The length across is 14
The adjacent is 10
The length of the shorter side is root 96
Use the pythagorean theorem
BC^2 = 14^2 - 10^2
BC^2 = 196 - 100, 96
BC^2 = root 96/14
Recall SOH-CAH-TOA
Adjacent over Hypotenuse is cos
That is how the answer is cos(x)
