Answer:
Step-by-step explanation:
To better understand the problem see that attached figure with letters
we know that
In the right triangle BCD
----> equation A
we know that
In the right triangle ABC
-----> equation B
equate equation A and equation B
Take the third equation and divide it by 2. If the equations are the same, they have infinitely many solutions because every point on one eq. is the same on the other. You can say they overlap.
Answer:
tan (C) = 2.05
Step-by-step explanation:
Given:
A right angled triangle CDE right angled at ∠D.
Side CD = 39
Side DE = 80
Side CE = 89
We know, from trigonometric ratios that, the tangent of any angle is equal to the ratio of the opposite side to the angle and the adjacent side of the angle.
Therefore, tangent of angle C is given as:
Plug in the given values and solve for angle C.This gives,
Therefore, the measure of tangent of angle C is 2.05.
Answer:
y = - 36x - 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 36 and c = - 9 , then
y = - 36x - 9 ← equation of line
F(6) means the value of function at 6.
This means we have to check the value of function against the value which is 6. First column is y. The last row of the the table shows y = 6 and the value of function at this value of y.
So the value of function at y = 6 is f(6) = 3
