Answer: 72 degrees for a, 108 degrees for b
Step-by-step explanation: Since the ratio of a to b is 3 to 2, 3x+2x would be 180 degrees. Performing addition and division, we would get 36 for x, and substituting it would get 72 degrees for a and 108 degrees for b. Hope this helps! (Could I please have brainliest?)
All you gotta do is divide 7 by 20
7 / 20 = 0.35
Answer:
Is this a test I cant help if not test I can help
Step-by-step explanation:
You can find the slope using the points.
9-18 -9 9
--------- = ------- = -------
-14+10 -4 4
Next, you can find the equation of the line.
y-9=9/4(x+14)
y=9/4x+40.5
Plug in 0 for x.
y=9/4(0)+40.5
y=40.5
So, the y-intercept is (0,40.5)
Plug in 0 for y.
0=9/4x+40.5
-40.5=9/4
x=-18
So, the x intercept is (-18,0)
I hope this helps!
Given:
Hexagonal Prism dimensions:
Altitude = 6 ft
Regular base;
side = 9 ft
apothem = 7.8 ft
The formula for the lateral surface area of a prism is
LA = P * h
where
LA is the lateral surface area
P is the perimeter of the base
h is the height of the prism
LA = (9 ft * 6 sides) * 6 ft
LA = 324 ft^2
The formula for total surface area is
TA = (P * h) + 2(Ab)
where
TA is the total surface area
Ab = Area of the base
Ab = a * P / 2
Ab = 7.8 ft * (9ft * 6) / 2
Ab = 210.6 ft^2
TA = 324 + 2(210.6)
TA = 745.2 ft^2
