That square in a means that it’s 90 degrees and b is 70. Well it says that ab = bc. And ab together is 90+70 which is 160. A straight line is 180 in total so to figure that other side of b out do 180-70 which is 110. So now you have 110, and to match ab you need 50 more degrees for bc. Therefore c is 50 degrees

tensa zangetsu [6.8K]

Answer:

First: 15

Second: 21

Third: 45

Step-by-step explanation:

In order to create the equation we need to represent the evenings with an alebraic term, in thsi case we are going to represent the second evening with an X

Second evening:x

The first night she got 6 fewer calls than the second: Second-6=x-6

The third night she received 3 times the first: 3(first night)=3(x-6)

The equation is First Night plus second night plus third night equals 81.

First+second+third=81\\x+(x-7)+3(x-6)=81\\x+x-7+3x-18=81\\5x=81+21+6\\5x=105\\x=\frac{105}{5} \\x=21

So the first evening he received 15 calls, the second he received 21 and the third one he received 45.
