y - y₁ = m(x - x₁)
y - (-10) = -1⁴/₂₁(x - 6)
y + 10 = -1⁴/₂₁(x) + 1⁴/₂₁(6)
y + 10 = -1⁴/₂₁x + 7¹/₇
- 10 - 10
y = -1⁴/₂₁x - 3¹/₇
Answer: 30°
Step-by-step explanation:
1. You know that:
- The length of the ladder is 30 feet.
- The window is located 15 feet above the ground.
2. Then, you can draw a right triangle as the one shown in the figure attached. So, you can calculate the angle asked as following:
Where:
α: the angle of the ladder with the ground.
opposite=15 feet
hypotenuse=30 feet
3. When you substitute values, you obtain:
°
