1 answer:
Answer:
Step-by-step explanation:
According to the Triangle Angle-Sum Theorem, all the angles of a triangle have to add up to equal 180 degrees. For us, in our triangle:
a + 2b + 70 = 180 so
a + 2b = 180 -70 and
a + 2b = 110. That's why.

Just divide then subtract
95/83= 1.14= move decimal to right one time so it would be 11.4 then subtract 11.4 from 95= 95-11.4= about $83.55
Multiply all of them together.10*9*8 and so on...
