Quadrilateral ABCD is inscribed in this circle. What is the measure of angle C? Enter your answer in the box.

i think the measure of angle C is 43.44 degrees

Step-by-step explanation:

the total amount of the angles within a box equals to 360 degrees so by just finding the angles, substitute angle C by x,  then adding all angles together and subtracting them to 360, the answer can be found.

x +20 + 2x + 38 + 3x + x= 360

7x + 58 = 360

7x = 302

x = 43.14

Then plugin 43.14 in the given angles

2(43.14) + 38 = 124 degrees

(43.14) + 20 = 63.14 degrees

3(43.14) = 129.42 degrees

Then add them together

138.66 + 70.33 + 150.99 = 316.56

Then subtract it with 360

360 - 316.56 = 43.44 degrees

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

the answer is a.
