Find the surface area and round to the nearest hundredths place when necessary.
Answers
Answer:
6 x 14 = 84
84 x 2(since there are two small rectangles) = 168
22 x 6 = 132
132 x 2 = 264
264 x 2(since there are two of the same shape) = 528
22 x 14 = 308
308 x 2(since there are two of the same shape) = 616
Now we add up all the areas:
168 + 528 + 616 = 1312 square cm is your answer.

B. ∠1 = 35°, m∠2 = 30°
C. ∠1 = 65°, m∠2 = 60°
D. ∠1 = 85°, m∠2 = 80°

The measure of m∠1 = 85 degrees and m∠2 = 15 degrees.
The correct answer is option D: ∠1 = 85°, m∠2 = 15°.
What is the right triangle?
A right-angle triangle is a triangle that has one of its angles 90 degrees. The sum of angles in a right triangle is 180 degrees.
To find the measures of angles 1 and 2, we can use the fact that the sum of the angles in a triangle is 180 degrees.
We know that angles 1, 2, and 3 form a triangle, so we can write:
m∠1 + m∠2 + m∠3 = 180
Substituting the given values, we get:
m∠1 + m∠2 + 80 = 180
Simplifying, we get:
m∠1 + m∠2 = 100
We also know that angles 2, 3, and 4 form a triangle, so we can write:
m∠2 + m∠3 + m∠4 = 180
Substituting the given values, we get:
m∠2 + 80 + 85 = 180
Simplifying, we get:
m∠2 = 15
Substituting this value in the first equation, we get:
m∠1 + 15 = 100
Simplifying, we get:
m∠1 = 85
Therefore, the measure of m∠1 = 85 degrees and m∠2 = 15 degrees.
The correct answer is option D: ∠1 = 85°, m∠2 = 15°.

Step-by-step explanation:
To find the x value of the vertex use the equation
-b/(2a)
-4/(2*2)= -1
this means that the x coordinate is -1
Now that we know the x value we need to find the corresponding y value
to do this we just plug in x into the equation
2(-1)²+4(-1)+2
2-4+2=0
put it all together and get (-1,0)
