Find the perimeter of the triangle.

Klio2033 [76]

9514 1404 393

Answer:

84 in

Step-by-step explanation:

The Pythagorean theorem is used to find the length 'b'.

b^2 +12^2 = 37^2

b = √(37^2 -12^2) = √1225 = 35

Then the perimeter is the sum of side lengths:

P = a + b + c = 12 + 35 + 37

P = 84 . . . inches

Answer:

51.7°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

Tan = Opposite/Adjacent

tan(D) = EF/FD = 95/75

D = arctan(95/75)

∠D ≈ 51.7°

HELP MEE PLZZZZ I DON'T UNDERSTAND THIS

Damm [24]

Answer: Choice D. $6.44 \times 10^{-4}$

========================================================

Work Shown:

We multiply the coefficients 9.2 and 7 to get 64.4, which is the same as 6.44*10^1 in scientific notation. When multiplying exponential expressions with the same base, we add the exponents

This is what the steps could look like

$\left(9.2 \times 10^{-9}\right)\times\left(7 \times 10^{4}\right)\\\\\left(9.2\times7\right)\times\left(10^{-9} \times 10^{4}\right)\\\\\left(64.4\right)\times\left(10^{-9+4}\right)\\\\\left(6.44\times 10^{1}\right)\times\left(10^{-5}\right)\\\\6.44\times\left(10^{1}\times 10^{-5}\right)\\\\6.44\times\left(10^{1+(-5)}\right)\\\\6.44\times 10^{-4}\\\\$

The final result is in scientific notation as the coefficient c is restricted such that $0 \le c < 10$
