so you are going to use the Pythagorean theorem on the smaller triangle to find the connecting side's length

${5}^{2} = {3}^{2} ( {b}^{2} ) \\ b = 4$

now you can find the bigger triangle's hypotenuse

${6}^{2} + {4}^{2} = {c}^{2} \\$

c=4

Can i pls have help with is soooooooooo confused

STALIN [3.7K]

500.

Solution: 210 is 42% of X

Equation: Y = P% * X

Solving our equation for X

X = Y/P%

X = 210/42%

Converting percent to decimal:

p = 42%/100 = 0.42

X = 210/0.42

X = 500
