Answer:
1. Right: pointing downwards
Left: pointing upwards
2. Right: pointing upwards
Left: pointing upwards
3. Right: pointing downwards
Left: pointing upwards
4a. True
4b. True
Step-by-step explanation:
When the leading coefficient is negative the equation will either open downwards or the y-values will decrease as the x-values increase. The opposite is true for when the leading coefficient is positive. When the degree is odd one end will point downwards while the other points upwards. When the degree is even, both ends point in the same direction.
I hope this helps :)
Step-by-step explanation:
By Exterior Angle Theorem,
81° + b = 117°.
=> b = 117° - 81° = 36°.
The area of a trapezoid can be found by the formula:
A = [(B + b) × h] / 2
where:
B = major base = 36 in
b = minor base = 30 in
h = height = 24 in
Therefore, with the given data you can calculate the area by applying the formula:
<span>A = [(36 + 30) × 24] / 2
= [66 </span><span>× 24] / 2
= 792 in</span>²
Hence, the area of the trapezoid is 792 in<span>².</span>

<u>Answer:</u>
∠NET = 63°
<u>Step-by-step explanation:</u>
We are given a figure with a circle A and a line ET which is tangent to the circle at the point T. Also, the measure of the angle TNG is given to be 27° and we are to find the measure of angle NET.
If we recall the point of tangency, we will remember that the point where a tangent touches the radius of a circle is always a right angle.
That makes the angle NTE to be 90°.
Putting the sum of these angles equal to 180 to get:
90 + 27 + ∠NET = 180
∠NET = 180 - 90 - 27
∠NET = 63°
