Answer:
Step-by-step explanation:
The useful relation in this geometry is: an exterior angle of a triangle is equal to the sum of the remote interior angles.
128° = ∠1 + 16°
112° = ∠1
__
112° = 86° +∠2
26° = ∠2
Answer:
D). (1, 0)
Step-by-step explanation:
The parabola opens to the right, so the focus will be to the right of the vertex at (0, 0). The only answer choice with a positive x-value is D.
___
The equation of a parabola with vertex (0, 0) can be written as
y^2 = 4px
where p is the distance from the vertex to the focus. Here, that distance is 1.
Answer:
12 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h(b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
Given h = 6, b₁ = 8 and A = 60 , then
× 6 × (8 + b₂ ) = 60 , that is
3(8 + b₂ ) = 60 ( divide both sides by 3 )
8 + b₂ = 20 ( subtract 8 from both sides )
b₂ = 12
The length of the second base is 12 inches
Answer:
B
How many times greater in the area of the signal from transmitter
2x -2x - 3 = 2x - 2x - 5 <em>subtract 2x from both sides</em>
-3 = -5 FALSE
<h3>Answer: D) no solution</h3>
