Answer:

  • opposite: 4.88
  • adjacent: 14.18

Step-by-step explanation:

SOH CAH TOA is a mnemonic intended to remind you of the relevant trig relations.

  Sin = Opposite/Hypotenuse   ⇒   opposite = 15×sin(19°) ≈ 4.88 units

  Cos = Adjacent/Hypotenuse   ⇒   adjacent = 15×cos(19°) ≈ 14.18 units

and since the sum of the angles in a triangle is 180 ,

the angle 1 is ..

180 - 29 - 84 = 67 degrees ,

therefore the answer is D

Help! If a = 57 in, b = 23 in, c = 72 in, and d = 26 in, what is the perimeter?
Oliga [24]

Answer: The correct answer is B. 350in

Step-by-step explanation: because there is one c, two a, four b, two d, and you have to add 20 for the extra space that didn’t have a measurement. So 72+57+57+23+23+23+23+26+26+20=350

In purchasing food for a political rally, you erroneously order shucked medium-size Pacific oysters (which come 8 to 12 per U.S.
creativ13 [48]

Answer:

The order is short of 1440 to 2080 oysters

Step-by-step explanation:

Volume of ship = 150cm × 11cm ×23cm = 37950cm^3 = 37950/1000 = 37.95L

I U.S. pint = 0.4732L

37.95L = 37.95/0.4732 = 80 U.S. pint (to the nearest whole number)

Order contains 8 to 12 oysters per U.S. pint

80 U.S. pint contains 8×80 to 12×80 oysters = 640 to 960 oysters

Anticipated count should contain 26 to 38 oysters per U.S. pint

80 U.S. pint should contain 26×80 to 38×80 oysters = 2080 to 3040 oysters

Shortage = (2080 - 640) to (3040 - 960) oysters = 1440 to 2080 oysters
