Answer:
Left: x = 56
Right: x = 58 1/2
Step-by-step explanation:
The <em>inscribed angle theorem </em>says that the inscribed angle subtended by an arc is half the measure of the central angle subtended by that same arc. In other words, if we had an arc with a measure of 12 degrees, its corresponding inscribed angle would be exactly 6 degrees, and if we had an inscribed angle measuring 10 degrees, it would be subtend an arc measuring 20 degrees.
On the left, we're given a measure of 28 degrees for the inscribed angle and have to find the measure of x, the subtended arc. Since 28 has to be half of x by the inscribed angle theorem, x must be 28 x 2 = 56°
On the right, we're given an arc with a measure of 117°, and we have to find the measure x° of the inscribed angle. Of course, this angle must be half of 117, so x = 117/2 = 58 1/2.

15+15=30
30/9=3 r3 doesn't work
30+15=45
45/9=5
I'm not sure what it is that you're looking for.
That'sa trinomial expression you've got there.
Its value depends on the value of theta.
Answer: supplement is 126 degrees 7
Step-by-step explanation: 2/3 of a right angle = (2/3 * 90) degrees = 60 degrees and its complement is 30 degrees 3/5 of a right angle = (3/5 * 90) degrees = 54 degrees and its is
supplement is 126 degrees 7
