Triangular pyramid has its base as a triangle, and a Rectangular pyramid has its base as a rectangle.
2 should be the correct answer!
Answer: 59 degrees
--------------------------------------------------------------
--------------------------------------------------------------
Work Shown:
We have the three angles:
angle A = (3x+2) degrees
angle B = (2x+7) degrees
angle C = 41 degrees
Rule: for any triangle, the three angles add up to 180 degrees
(angle A) + (angle B) + (angle C) = 180
(3x+2) + (2x+7) + (41) = 180
3x+2 + 2x+7 + 41 = 180
(3x+2x)+(2+7+41) = 180
(5x)+(50) = 180
5x+50 = 180
5x+50-50 = 180-50
5x = 130
5x/5 = 130/5
x = 26
Now use this x value to find the measure of angle B
angle B = (2x+7) degrees
angle B = (2*x+7) degrees
angle B = (2*26+7) degrees
angle B = (52+7) degrees
angle B = 59 degrees
Side Note: Angle A is 80 degrees (3x+2 = 3*26+2 = 78+2 = 80)
Another thing to note: A+B+C = 80+59+41 = 180
Answer:
B. y > 2/3x + 1
Step-by-step explanation:
To find slope we'll use the following formula,
(-3,-1) (3,3)
3 - -1 = 4
3 - -3 = 6
2/3x
The y intercept is 1,
we know this because that's the point the line touches the y axis.
<em>Thus,</em>
<em>the answer is B</em><u><em>. y > 1/3x + 1</em></u><em>.</em>
<em>Hope this helps :)</em>
