Trigonometry can be used to find angles and sides of simple triangles. If an 18-foot ladder touches a building 14 feet up the wall then the angle can be deduced by trigonometry. In this case, the ladder defines the hypotenuse (H) of the triangle and the wall defines the opposite (O) side of the triangle. Therefore we can use the equation theta=sin^-1(O/H) . This yields an angle of 51 degrees.
Answer:
Proud of you!! <3 :)
Step-by-step explanation:
(32°) = 1700 feet / x => x = 1700 feet / tan(32°) = 1700 feet / 0.625 = 2720 feet.
ANSWER
X = -9
EXPLANATION: you subtract 180 - 70 giving you 110
Equation set up: x + 49 + x + 79 = 110
Answer:
ASA
Step-by-step explanation:
The Angle Side Angle Postulate (ASA) says that "triangles are congruent if any two angles and their included side are equal in the triangles. An included side is the side between two angles."
Hope this helps! :)
