Answer:
angle LKJ = 49 degrees
Explanation:
Triangle JKL is a right-angled triangle. This means taht the special trigonometric functions can be applied.
These trig functions are:
sine θ = opposite side / hypotenuse
cos θ = adjacent side / hypotenuse
tan θ = opposite side / adjacent side
In the given:
θ is angle LKJ
the opposite side is LJ = 8.9 cm
the adjacent side is LK = 7.7 cm
using the tan of the angle:
tan (LKJ) = 8.9 / 7.7
angle LKJ = tan^-1 (8.9 / 7.7)
angle LKJ = 49.134 which is approximately 49 degrees
Hope this helps :)
Answer: angle 2 is 49°
explanation: the interior angles of all triangles add up to 180°, so just subtract the known angles from 180 to get the unknown angle:)
The value of x in the diagram is 8 feet that makes the combined area of the house and the porch to be 733 ft²
<h3>How to calculate
area?</h3>
Combined area = big rectangle + smaller rectangle - triangle
Hence:
733 = (13 * (59 - x)) + (x * 9) - 0.5(9 - 7) * (x - 6)
733 = 767 - 13x + 9x - x + 6
x = 8 feet
The value of x in the diagram is 8 feet that makes the combined area of the house and the porch to be 733 ft²
