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 
.
Here 12.9'[''''''''''''''''''''''''''''''''
672,591 is rounded to 700,000.
Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
4x + 3y = 1 → (1)
x - 3y = - 11 → (2)
Adding the 2 equations term by term will eliminate the y- term
5x + 0 = - 10
5x = - 10 ( divide both sides by 5 )
x = - 2
Substitute x = - 2 into either of the 2 equations and solve for y
Substituting into (1)
4(- 2) + 3y = 1
- 8 + 3y = 1 ( add 8 to both sides )
3y = 9 ( divide both sides by 3 )
y = 3
solution is (2, - 3 )
It is C. arithmetic
hope this helps
