Use trigonometry to solve word problem with angle of elevation

The video tutorial explains a simple trigonometry problem involving an angle of elevation. It starts with setting up the problem, identifying the angle of elevation, and the distance between two points. The instructor then chooses the tangent function to solve for the height, emphasizing the importance of using correct units and calculator settings. The tutorial concludes with the final calculation and a brief recap.

What is the angle of elevation in the problem setup?

• 30 degrees

• 45 degrees

• 52 degrees

• 60 degrees

Which trigonometric function is used to solve the problem involving the angle of elevation?

• Tangent

• Cosine

• Sine

• Cotangent

What is the formula used to calculate the height in this problem?

• Height = 120 feet / cosine of 52 degrees

• Height = 120 feet * tangent of 52 degrees
