Answer:
4 cats
18 dogs
18 x 4.5 = 81
4 x 1.0 = 4
81 + 4 = 85.00
22 ÷ 2 = 11
Start there and just numbers and cost till you find the right numbers

Answer:
a = 57.5
b = 90
c = 65
Step-by-step explanation:
The measure of an inscribed angle is half that of the arc it intercepts. The angle at 'a' intercepts an arc of 115°, so its measure is (115/2)° = 57.5°
__
The inscribed angle at 'b' is a semicircle, 180°, so the measure of 'b' is (180/2)° = 90°.
__
The arc 'c' is the remainder of a semicircle after 115° have been taken away. Its measure is 180° -115° = 65°.
(a, b, c) = (57.5, 90, 65)
