What is the value of a if va- vh is equals to 1

​

Step-by-step explanation:

we want to figure out a value of a for the following condition

to do so factor out v;

divide both sides by v which yields:

therefore,

now,add h to both sides:

further simplification if necessary:

factor out of v

Dividing both sides by (v)

cancel out (v)

add h in both sides

cancelout h

the value of a if va- vh is equals to 1 is

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
