Answer:
22 units
Step-by-step explanation:
The formula for the area of a trapezoid is A = 
where a and b are the <u>bases</u> and h is the <u>height</u> of the trapezoid.
In this case, the numbers that will be replacing a and b will be 4 and 7, making the equation look like this: A = 
.
Now, you have to determine the height of the trapezoid, which in this case is 4 units. The equation will now look like this: A = 
.
You can solve from here like so:
A = 
A = 5.5(4)
A = 22
sorry that took long :3))
I got the measurements like 4, 7, and the other 4 from rotating the shape to have the longer side on the bottom.
Answer:
x=6
Step-by-step explanation:
12x+6=78
or, 12x=72
or, x=72/12
or x= 6
Answer:
∠AOB and ∠COD are vertical angles
∠DOE and ∠COD are complementary, adjacent
∠AOB and ∠AOD are supplementary, adjacent.
Step-by-step explanation:
Let's start with ∠AOB and ∠COD.
Looking at this, we can see they are the same angles formed by two lines that intersected. These are vertical angles as they are opposite each other.
∠DOE and ∠COD together form the angle ∠EOC, which is a right angle. Complementary angles are any of two that add up to 90°, so these two angles are complementary. They are also adjacent because they are right next to each other.
∠AOB and ∠AOD together form the angle ∠BOD, which has a measure of 180°. Supplementary angles are any of two that add up to 180°, so ∠AOB and ∠AOD are supplementary. They are also adjacent as they are touching/right next to each other.
I hope this helped!
Answer:
1.5 or 1/5
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
It's 0.28 because 7 is greater than 4 so you round the number before that up by 1
