Answer:
24 units^2
Step-by-step explanation:
bc=6
ab=8
area of a triangle: b*l/2
6*8/2=24
Before attempting to solve this question, we must first know three things.
1. A straight line has a measure of 180 degrees.
2. When two angles add up to 180 degrees, those angles are called supplementary.
3. The interior angles of a triangle add up to 180 degrees.
We can see ∠ECT = 180 degrees.
∠DCT is supplementary to ∠DCE.
∠DCT = 140 degreees
∠DCE = x degrees
x + 140 = 180
Solve for x.
x + 140 = 180
x = 40 <-- Subtract 140 from each side
∠DCE = 40 degrees
We know the two interior angles of ΔDEC.
45 + 40 + x = 180
Solve for x.
45 + 40 + x = 180
85 + x = 180 <-- Combine like terms
x = 95
So, the missing angle is equal to 95 degrees.
If there were two electricians, they'd need to install 48 fixtures per person.. if it takes 20 minutes for each fixture, it would take a total of 960 minutes, which converts to 16 hours. If a work day was only 8 hours, it would take two electricians TWO work days to install 96 light fixtures, or 24 light fixtures for four floors.
Answer: 1 1/2 inches
Step-by-step explanation:
You can divide each part of the fraction by 4 to simplify it to 1/2, which is still equivalent to 4/8. This makes your simplified answer 1 1/2, or 1.5 in decimal form.
