Answer:
Step-by-step explanation:
Step-by-step explanation:
The first equation can be written as:
2x = 5 + 3y
Substituting the second equation into the first equation and rearranging:
-4y - 16 = 5 + 3y
-21 = 7y
y = -3
Substituting y = -3 into the second equation:
x = -2(-3) - 8
x = -2
AB is a diameter of the circle, so it divides circle into two semicircles.
Inscribed Angle Theorem:
The measure of an inscribed angle is half the measure of the intercepted arc.
An especially interesting result of the Inscribed Angle Theorem is that an angle inscribed in a semi-circle is a right angle. That's why m∠<span>AQB=m∠</span><span>ASB=m∠</span><span>ALB=m∠</span><span>ATB=m∠</span><span>ARB=90°.</span>
It is impossible to find measure of ∠<span>BWD, its measure depends on measure of a central angle ∠WDB. </span>
