The inscribed triangle is a right triangle. The diameter of the circle served as the hypotenuse of the triangle.
Angle C is 90°
Angle D = 36°/2 = 18°
<span>The measure of ∡DBC?
</span>
180° - 90° - 18° = 72°
Remember that interior angles of a triangle sum up to 180°.
Answer:
m =64/3
Step-by-step explanation:
m=21 1/3 m=21.3
50 + 3x = 7x + 12
This is because of the exterior angle theorem.
