<span> Let side a = 5. Let side b = 9. Then the triangle has sides a=5, b=9, and c=?. Any side of a triangle must be less than the other two sides added together, so a < b+c, b < a+c, and c < a+b Substituting: 5 < 9+c, 9 < 5+c, and c < 5+9 Solving all three for c: -4 < c, 4 < c, c < 14 The first one is of course true, so ignore it. Put the second and third together and get 4 < c < 14 <span>

Find the measure of XCY. PLEASE HELP ME AND SHOW WORK
Dovator [93]

Answer:

Measure of angle XCY is 60°.

Step-by-step explanation:

"Measure of all inscribed angles by the same arc in one segment of the circle are equal"

Using this property in the given circle,

m∠XWY = m∠XCY

60x = 61x - 1

61x - 60x = 1

x = 1

By substituting the value of 'x' in the measure of ∠XCY,

m∠XCY = 61x - 1

             = 61(1) - 1

             = 61 - 1

             = 60°

Therefore, measure of angle XCY is 60°.
