Answer:
The first one is 141 degrees, the second one is 39 degrees, the third is 149 degrees, the fourth one is 98 degrees, the fifth one is 102 degrees, the sixth one is 50 degrees, the seventh one is 74 degrees, the eighth one is 83 degrees, the ninth one is 95 degrees, the tenth one is 162 degrees.
Step-by-step explanation:
Basically you can look at the lines and tell if they are the same degree or not and if they are not you subtract that number from 180 to get your degree. I've already done this worksheet before and got a 100%
Answer:
Let's split the figure first:
9 x 5 = 45(area of small rectangle on top)
18 - 5 = 14(height)
17 - 9 = 8(width)
14 x 8 = 112(area of rectangle in the middle nearly)
18 - 5 = 14(base)
5(base 1) + 14(base 2) = 19
17 - 9 = 8(height)
19 x 8 = 152
152 divided by 2( x 1/2) = 76(area of a trapezoid on the side)
Now let's add all the given areas:
45 + 112 + 76 = 233 in^2 is your answer.
Answer:
1,749
8,349
Step-by-step explanation:
We can multiply 6,600 by 1.265 to get 8,349. To get the percentage all we have to do is multiply 6,600 by .265 and get 1,749.

Answer:
(-1,-18) is the coordinate of the vertex.
Step-by-step explanation:
We can obtain the vertex by taking the derivative and equating it to zero. I know this because the the slope of the tangent line at the vertex has to be equal to zero.
the derivative would be 4x + 4 = 0, where x = -1.
Plugging x into the original value we will end up with the y coordinate.
Hope this helps.
Answer:
90°
Step-by-step explanation:
note that 
simplifies to 
There are 360° in one turn of the circle , then
× 360° = 360° ÷ 4 = 90°
