Line segment xy is tangent to circle z at point u. if the measure of is 84°, what is the measure of ? 42° 84° 96° 168°

The measure of angle YUV is equal to

Step-by-step explanation:

see the attached figure to better understand the problem

we have that

-----> given problem

so

------> by central angle

we know that

The triangle UZV is an isosceles triangle

because

so

-----> bases angle of the isosceles triangle

Remember that

The sum of the internal angles of a triangle is equal to

so

substitute and solve for m<ZUV

------> by complementary angles

solve for m<YUZ
