Answer:
The measure of ∠D = (Q) = 28.81
Step-by-step explanation:
Tan(Q) = perpendicular/ base
In this case perpendicular is BC and base is DC
BC =25 DC = 45
Tan(Q) = BC/DC
Tan(Q) = 25/ 45
Tan(Q) = 5/ 9
(Q) = tan^ -1 (0.55)
(Q) = 28.81
The area, which is L x W.
L = x+14
W = x-20
Therefore, LW or (x+14)(x-20) is the area
The formula for the sum of the measures of a polygon's interior angles is 180(n-2), where n is the number of sides.
3060 = 180(n-2)
17=n-2
19=n
Therefore, the polygon has C. 19 sides.
Hello, and welcome to Brainly!
It seems y ou want to find the value of x in the expression -4x + 7 - 6 = 22.
If that's the case, combine the 7 and -6, obtaining: -4x + 1 = 22. We want to isolate x. To achieve this, subtract 1 from both sides, obtaining -4x = 21.
Dividing both sides of this equation by -4 gives us x = (-21)/4.
This is the "solution" of the given equation.
