Answer:
73°
Step-by-step explanation:
Here we use trigonometry to find the angle. The building and the ground form a perpendicular angle, with the ladder acting as the hypotenuse, we get a right angle. We know the length of adjacent leg from the angle, and the length of the hypotenuse. In this case, we use cosine since cos = adjacent length/hypotenuse length. So cos x= 7/24. To isolate x, we use the inverse function of cos, cos^-1. Then x= cos^-1 (7/24) or 73°.
It is because benchmark fraction 1/5 = .20
Answer:
Step-by-step explanation:
Given: 
To find: angle to the nearest degree
Solution:
A triangle is a polygon that has three sides, three angles ,and three vertices.
Trigonometry explains the relationship between the sides and angles of the triangle.
The angle can be expressed in two forms: degrees or radians.
Answer:
.25881
Step-by-step explanation:
sin15
=sin(45-30)
=sin45.cos30-cos45.sin30
=(0.707×0.86)-(0.707×0.5)
=(0.6082)-(0.3535)
=0.25
It looks like the ∩ sign may be missing from the question. If you mean to find A∩C, called the intersection, you're looking for elements that are both in A and C.
{0, 2} qualifies.
