Given:
In ΔFGH, the measure of ∠H=90°, FH = 39, GF = 89, and HG = 80.
To find:
The ratio which represents the cotangent of ∠G.
Solution:
In a right angle triangle, the ratio of the cotangent of an angle is
It is also written as
In ΔFGH, the measure of ∠H=90°. So,
Therefore, the ratio for the cotangent of ∠G is .
Answer: Choice D)
===========================================================
Work Shown:
Point A starts at (-2,3) and moves to (2,5) after applying the translation rule of "shift 4 to the right, 2 up".
Use the distance formula to find the distance from (-2,3) to (2,5)
Given:
Sharon uses 6.3 pints of blue paint and white paint to paint her bedroom walls.
of this amount is blue paint and the rest is white paint.
