What is the length of the unknown leg in the right triangle?
25 m
20 m
O v5 m
O 5m
O 145 m
15 m

The length of the unknown leg is 15m

Step-by-step explanation:

To calculate the unknown leg we need to use Pythagoras

h = hyoptenuse = 25m

a = leg 1 = 20m

b = leg 2

h² = a² + b²

we replace with the known values

(25m)² = (20m)² + b²

625m² = 400m² + b²

625m² - 400m² = b²

225m² = b²

√225m² = b

15m = b

The length of the unknown leg is 15m

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

i am not sure

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
