Answer:
3.5% Error
Step-by-step explanation:
I used this equation - 100 * (1 - (75.5/78.25)) = 3.514376...(Rounded to the tenths place you get 3.5)
Breakdown: You want to get your error to do this first you get your percent that was correct which is - (75.5/78.25)
You then subtract this by one because this will give you your margin of error as a decimal hence - (1 - (75.5/78.25))
Lastly, multiply this by 100 because you want to convert the decimal into a percent then round to the nearest tenth of a percent resulting in 3.5% error.
Answer:
Angle 1 equals 90 degrees. Angle 2 equals 38 degrees.
Step-by-step explanation:
Angle 1 is at the cross of two perpendicular lines, making it 90 degrees. Angle 2 can be found by making the two equal side lengths and the middle line into one triangle. This means that two of the angles are 52 degrees. This leaves 76 degrees to be split in the triangle. The middle line cuts the angle in half, making it 38 degrees
Answer:
vol = 96
Step-by-step explanation:
Area of a triangle = 1/2 * b * h
b = 4
h = 6
A = 0.5 * 4 * 6
A = 12
length = 8
vol = Area * length
vol = 12 * 8
vol = 96
