Answer:

  30°

Step-by-step explanation:

The relationship between triangle sides and angles can be remembered using the mnemonic SOH CAH TOA. Here, we're interested in the relationship involving the hypotenuse and the side opposite the angle:

  Sin = Opposite/Hypotenuse

For a ramp 1 m high and 2 m long, we have ...

  sin(x) = (1 m)/(2 m) = 1/2

  x = arcsin(1/2) = 30°

The elevation angle of the ramp needs to be 30°.

What is the answer to this equation? Algebra 1 . |10-6r| -3 = 13 ??
LUCKY_DIMON [66]

Answer:

r = -1 or r = 13/3

Step-by-step explanation:

Solve for r over the real numbers:

abs(10 - 6 r) = 16

Split the equation into two possible cases:

10 - 6 r = 16 or 10 - 6 r = -16

Subtract 10 from both sides:

-6 r = 6 or 10 - 6 r = -16

Divide both sides by -6:

r = -1 or 10 - 6 r = -16

Subtract 10 from both sides:

r = -1 or -6 r = -26

Divide both sides by -6:

Answer: r = -1 or r = 13/3
