Look at triangle STU: A right triangle STU is shown with the right angle at T. The length of side ST is labeled as 42 cm, and the length of side TU is labeled as 56 cm.

What is the length (in centimeters) of side SU of the triangle?

70 centimeters
77 centimeters
90 centimeters
98 centimeters

70 cm

Step-by-step explanation:

42^2 + 56^2 = c^2

1764 + 3136 = c^2

4900 = c^2

70 = c

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

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!
