Typical story problem where you have to take the written words and put them into some sort of usable equation. "3 times the measure of an angle is" looks like this in equation form: 3x = , where x is the measure of the angle and the word :"is" means equals. A complement is 90 - the measure of the angle, so 90 - x, and 14 less than that indicates we are subtracting 14 from that complement. In the end, the equation is this: 3x = (90 - x) - 14; 3x = 76 - x; 4x = 76 and of course x = 19. These darn story problems...
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 :)
