I think this is right, her average grade is 85%
Answer:
48.2°
Step-by-step explanation:
If a 15' ladder is leaned up against a building so that the bottom of the ladder is 10' from the base of the building, what angle does the ladder make with the ground
Let the angle the ladder makes with the ground be represented by x
We solve the above question using the Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = 10 inches
Hypotenuse = 15 inches
Hence,
cos x = 10/15
x = arc cos (10/15)
x = 48.189685104°
Approximately = 48.2°
Therefore, the angle the ladder makes with the ground is 48.2°
TSP makes a right triangle with TS and TP being the sides and SP being the hypotenuse.
Using the Pythagorean theorem and the two given sides you can solve for the hypotenuse.
SP = √6^2 + 8^2
SP = √36+64
SP = √100
SP = 10 cm.
