Answer:
x = 30
Step-by-step explanation:

Answer: <em>1=60°</em>
Step-by-step explanation:
<em>First, let's take our given angle of 30°</em>
<em>30° is in a right triangle, so the angles must be 90°, 60°, and 30°</em>
<em>Now the angle that is 45° makes angle 1 congruent to angle 60°</em>
<em>Meaning angle 1 is </em><em>60°</em>
The independent variable, x, represents the SIDE LENGTHS, and the dependent variable is the PERIMETER, because the PERIMETER, depends on the SIDE LENGTHS.
Xa+xb+21+2b is the answer
Answer:
A
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x² + 4x - 8 - (2x - 5) ← distribute parenthesis by - 1
= 3x² + 4x - 8 - 2x + 5 ← collect like terms
= 3x² + 2x - 3 → A
