Answer:

27 degrees and 63 degrees

Step-by-step explanation:

Let n be the number.

Angle 1: 2n-15

Angle 2: 3n

If the angles are complementary they add up to 90.

Therefore we can write an equation.

2n-15+3n=90

Combine like terms

5n-15=90

Add 15 to both sides

5n=105

n=21

Now we plug 21 in for n and solve for the angles

Angle 1 = 2(21)-15

Angle 1 = 42-15

Angle 1 = 27

Angle 2 = 3(21)

Angle 2 = 63

Question 2
FrozenT [24]

Answer:

y=-3x-1

Step-by-step explanation:

<u>Slope-intercept format:</u>

y = mx+b

m = slope

  • In this case, the slope is -3

b = y-intercept

  • In this case, the y-intercept is -1

Now we plug it in to get the equation:

y=-3x-1

I hope this helped!

Sincerely,

Answer:

m(arc FE) = 166°

Step-by-step explanation:

By theorem of intersecting chords and tangent of a circle,

Measure of the angle formed by a chord and tangent intersecting on the circle measure the half of the intercepted arc.

m(∠GFE) = \frac{1}{2}\text{m (arc} FE)

83° = \frac{1}{2}\text{m (arc} FE)

m(arc FE) = 166°
