Answer:

x ≈ 136.7 ft

Step-by-step explanation:

As you have marked, the relevant sides are the adjacent side and the hypotenuse. The mnemonic SOH CAH TOA reminds you ...

Cos = Adjacent/Hypotenuse

For this triangle, that means ...

cos(43°) = (100 ft)/x

x = (100 ft)/cos(43°) . . . . . . . . . . multiply both sides by x/cos(43°)

x ≈ 136.73 ft

The length x is about 136.7 feet.

$5x + (6x - 5) + (3x + 10) = 360$

$5x + 6x - 5 + 3x + 10 = 360$

$11x - 5 + 3x + 10 = 360$

$14x + 5 = 360$

$14x = 360 - 5$

$14x = 355$

$x = 25.36$

$x = 25.36$

$5x = 5 \times 25.36 = 126.8$

$6x - 5 = 6 \times 25.36 - 5 = 147.16$

$3x + 10 = 3 \times 25.36 + 10 = 86.08$

Oman said that it is impossible to raise a number to the power of 2 and get a value less than the original number.Do you agree w

disa [49]

That’s false, if you raise a number that’s less than 1 to the second power, you’d get a lesser number.
For example, if you raise 1/2 to the second power, you’d get 1/4
