Answer:

Look at the answers bolded below

Step-by-step explanation:

To get the reference angle, just subtract 115° from 180°

180 - 115 = 65

So the reference angle is 65°

I'm not sure how many coterminal angles you need, but to get them you could just add or subtract 360°.

For example, a positive coterminal angle could be:

115 + 360 = 475°

a negative coterminal angle could be:

115 - 360 = -245°

Hope this helped :)

Need help thanks!! Don't know how to solve problem

Nina [5.8K]

The measure of the angle formed by 2 chords that intersect inside the circle is 1/2<span> the sum of the chords' intercepted arcs.
</span>
(83 + x)/2 = 107
83 + x = 107 * 2
83 + x = 214
x = 214 - 83
x = 131°

What is the value of d? Assume that the line is a tangent to the circle.

motikmotik

We have been given a chord and tangent to a circle. We have been minor arc measure that is equal to $118^{0}$ .

Since we know that angle formed by a secant and tangent of circle is half of the measure of intercepted arc.

$\measuredangle x=\frac{1}{2}m \widehat{ABC}$

We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.

$360^{0}-118^{0}=242^{0}$

Now we will plug given values in our formula,

$d^{0}=\frac{242}{2}=121$

Therefore, the measure of d is 121 degrees.
