Answer:
90°
Step-by-step explanation:
Arc a subtends and angle of 45° to the circumference of the circle
We know that;
An angle subtended by an arc to the center of a circle is twice the angle subtended by the same chord to the center of the circle.
Therefore, if arc a subtends and angle of 45° to the circumference of the circle then;
a will be = 45 × 2
= 90°
Answer:
697.24 and 886.76
Step-by-step explanation:
792+.92*103= 886.76

if that's not correct try 697.76 and 886.25
Answer:
Step-by-step explanation:
Solving an inequality is similar to solving an equation. To solve for r, isolate it. Whatever you do to one side, do to the other. Remember that a negative and a negative equal a positive, thus one side of the inequality becomes r + 5. Then, subtract both sides by -5 to find the answer.
