she got 95 questions right → 95% = = 0.95
answer:
x = 4 or 5.6568
step-by-step explanation:
- know the formula and plug in
formula: a^2 + b^2 = c^2
- now plug in what we have
- whatever the RIGHT ANGLE points to is the HYPOTENUSE or c
- the other two sides are the "legs" or a and b
a^2 + b^2 = c^2
7^2 + b^2 = 9^2
49 + b^2 = 81
b^2 = 32
b = 4
- in this case, b would be used as x
x = 4 or 5.6568 (exact value)
