Please help me on math

45 inches

Step-by-step explanation:

85-40=45

b=45

how I know?

use the formula c^2-a^2=b^2

85 being c, a being 40 and b being 45

Hello! b = 75

Step-by-step explanation:

We have to find b so we have to work backwards to find the answer the steps would be to find c^2 subtract that by a^2 and then you get b^2 and have to find out what multiplied by itself equals b^2 so... 85 × 85 = 7225 40 × 40 = 1600 7225 - 1600 = 5625 75 × 75 = 5625 therefore b = 75 hope that helps!
