Please consider the attached diagram.
We have been given that angle DAB and angle DCB are right angles. We are also told that measure of angle DBC is 42 degrees. We are asked to find the measure of arc CAB.
We can see that angle DBC is inscribed angle of arc DC, so measure of arc DC is two times the measure of angle DBC.
We can also see that segment DB is diameter of given circle as inscribed angle of diameter is a right angle.
Since segment DB is diameter of given circle, so measure of arc DAB would be equal to half the measure of 360 degrees.
Therefore, the measure of arc CAB is 264 degrees.

Answer: 131 degrees</h3>
Work Shown:
(angle JIW) + (angle WIH) = angle JIH
(2x+8) + (101) = 11x + 10
2x+109 = 11x+10
2x-11x = 10-109
-9x = -99
x = -99/(-9)
x = 11
So,
- angle JIW = 2x+8 = 2*11+8 = 22+8 = 30 degrees
- angle WIH = 101 degrees
- angle JIH = 11x+10 = 11*11+10 = 121+10 = 131 degrees
The smaller angles add to 30+101 = 131 to confirm we have the correct answer.

The answer is 0
This is because anything times 0 is zero.
Answer:
The answers are:
m = 9 and n = 15
Step-by-step explanation:
m/15 = n/25 = 12/20
m/15 = 12/20
m/15 = 3/5
5m = 45
m = 9
n/25 = 12/20
n/25 = 3/5
5n = 75
n = 15
