Put the negative exponent as the denominator in a fraction, so you'd get -7/1
When you know your equation f(x) and they want you to find f(-4), it means that they want to know what f(x) is worth when x=-4
Therefore, you only need to plug in you x in the equation
f(x)=5x-2
f(-4)=5(-4)-2
=-20-2
=-22 (B)
M=30° because the right angle and 60 degree angle equal 150 and 180 (degrees in a triangle) minus 150 is 30
n=50° because 40 plus the right angle is 130 then the difference between that and 180 is 50 then n is the vertex angle of the one you found
t=98° because answer n plus the other part to the straight angle including the 112° angle is 68 then the total angle turns to 118 then the final angle turns to 62 via earlier reasoning, then because of another straight angle t=98
use the earlier reasoning to fine the other answers of
p=71°
q=39°
use the angle degrees formula to get Pentagon's maximum angles then use earlier resources
the final answers u should be able to figure out from there and u will never learn unless you do some yourself

Answer:
Step-by-step explanation:
Angle A = 90°
Angle B = 45°
According to the angle sum property
Angle A + Angle B + Angle C = 180°
90° + 45° + Angle C = 180°
Angle C = 45°
As the two angles are equal so the triangle is right angle isosceles triangle.
