Answer:
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
Answer:
4
Step-by-step explanation:
The sum of the measures of all interior angles in triangle is always equal to 180°. So,
∠A+∠B+∠C=180°
∠B=180°-63°-49°=68°
Now use the sine rule:
