5x + 25y = 60....multiply by -3
3x + 15y = 42....multiply by 5
-------------------
-15x - 75y = - 180 (result of multiplying by -3)
15x + 75y = 210 (result of multiplying by 5)
-------------------add
0 = 30...incorrect.....this system has no solutions

Keegan leans an 18-foot ladder against the top of a wall. The bottom of the ladder is 4.5 feet from the base of the wall. What i
zaharov [31]

Answer: C. 17.5 feet

Step-by-step explanation:

The attached photo shows the triangle ABC formed by the ladder and the wall. It is a right angle triangle because one of its angles is 90 degrees. The ladder is the hypotenuse of the triangle. To determine the height of the wall, we would find BC by applying Pythagoras theorem

Hypotenuse^2 = opposite ^2 + adjacent^2

18^2 + 4.5^2 + BC^2

BC^2 = 324 - 20.25 = 303.75

BC = √303.75 = 17.5 feet.

  • x/9 = cos 48°
  • x = 9 cos 48°
  • x = 6.0

2.

  • x/11 = sin62°
  • x = 11 sin 62°
  • x = 9.7

3.

  • x/8 = tan 75
  • x = 8 tan 75°
  • x = 29.9

4.

  • sin x = 38/53
  • x = arcsin 38.53
  • x = 45.8°

5.

  • tan x = 15/20
  • x = arctan 15/20
  • x = 36.9°

6.

  • cos x = 27/29
  • x = arccos 27/29
  • x = 21.4°
