Given:
Circle with chord and tangent.
To find:
The measure of angle 1.
Solution:
Let 2 be the adjacent angle of angle 1.
If a tangent and a chord intersect at a point, then the angle formed is half of the measure of the intercepted arc.
Sum of the adjacent angles in a straight line is 180°.
⇒ m∠1 + m∠2 = 180°
⇒ m∠1 + 124° = 180°
Subtract 124° from both sides.
⇒ m∠1 = 56°
The measure of angle 1 is 56°.
Answer:
q=15
Step-by-step explanation:
1/5q=9-2/5q
Multiply both sides by 5
q=9*5-2q
3q=45
q=15
Answer:
your answer should be 45

Answer:
1,436.9 in
Step-by-step explanation:
V=πr²(h/3)
V=π(9.9)²(14/3)
V=1,436.9 in
Hi there,
your question is asking for the angle of the central circle, and the formula is: the two arcs' sum divided by 2
So,
(60 + 40) ÷ 2 = 50
The answer is 50°
Hope I helped :p
