Angle 2 of what? kinda non descriptive
Answer:

Step-by-step explanation:

Answer:
3√150
Step-by-step explanation:
I can't really explain it sorry but I'll try my best...
Option 1. Use a calculator to find the square root by inputing √150
Option 2. Option 1 is the only possible way because you cannot use trial and error as the number will never be exact, that is why the answer is represneted the way it is.
F(x) = -4x + 7
g(x) = 10x - 6
f(g(x)) = -4(10x - 6) + 7
f(g(x)) = -4(10x) + 4(6) + 7
f(g(x)) = -40x + 24 + 7
f(g(x)) = -40x + 31
Answer:
m∠C=30°
Step-by-step explanation:
we know that
<u>Vertical Angles</u> are the angles opposite each other when two lines cross. They are always equal
so
m∠C=m∠D
substitute the given values

Solve for x

<em>Find the measure of angle C</em>
m∠C=(x+5)°
substitute the value of x
m∠C=(25+5)=30°
