a² + b² = c²
a² + 1.8² = 2.5²
a² = 2.5² -1.8²
a² = 3.01
a = √3.01 = 1.7m (nearest tenth)
Answer: The height of the tentpole is 1.7m tall.
cos (x) = 1.8/2.5
cos (x) = 0.72
x = cos⁻¹ (0.72)
x = 43.9° (nearest tenth)
Answer: The angle is 43.9°
The answer would be 44.9 yard.
Answer:
13,92838827718412ft
Step-by-step explanation:
a = 13ft
b = 5ft
169 + 25 = 194
c = √194
c = 13,92838827718412ft
