∠ACB is an inscribed angle, so
m∠ACB= (1/2)mAB =(1/2)*50=25⁰
m∠ACB= 25⁰
Answer:
8
Step-by-step explanation:
It is given in the question that
Ann, Chang, and Kareem sent a total of 89 text messages over their cell phones during the weekend. Ann sent 9 fewer messages than Chang. Kareem sent 3 times as many messages as Ann.
Let number of messages Chang sent be x. And Ann sent 9 fewer than Chang, so Ann sent (x-9) messages. And Kareem sent 3 times as many messages as Ann, so Kareem sent 3(x-9) messages.
And the total messages are 89. That is
![x+x-9+3(x-9)=89](https://tex.z-dn.net/?f=x%2Bx-9%2B3%28x-9%29%3D89)
Combining like terms
![x + x - 9 + 3x-27 =89 \\ 5x -36=89 \\ 5x = 125 \\ x =25](https://tex.z-dn.net/?f=x%20%2B%20x%20-%209%20%2B%203x-27%20%3D89%0A%5C%5C%0A5x%20-36%3D89%0A%5C%5C%0A5x%20%3D%20125%0A%5C%5C%0Ax%20%3D25)
So Chang sent 25 messages, Ann sent
![25-9=16 messages](https://tex.z-dn.net/?f=25-9%3D16%20messages)
And Kareem sent
![3*16 = 48 messages](https://tex.z-dn.net/?f=3%2A16%20%3D%2048%20messages)
