1. Triangle ABC is a right triangle with right angle at B.
AB=29cm
CB=38cm
What is the measure of C to the nearest degree?
2. Which equation correctly describes the relationship between the measure of inscribed angle and the measure of the intercepted arc in the figure?
Options- mPQR=360dg-m(arc)PR, mPQR=2(m arc PR), mPQR=1/2m(arc)PR, mPQR=m(arc)PR
3. In circle Q, what is the value of x?
+128406 1.
A
B C
AB = 29 CB = 38
We can use the tangent inverse to find C
arctan ( 29/38) = C ≈ 37.35°
2. mPQR=1/2m(arc)PR
3. This iis a right triangle where the right angle intercepts the diameter......the sum of the other two angles = 90...so...
x + 54 = 90
Subtract 54 from both sides
x = 36
