we know that

so
<u>Find the value of the scale factor</u>

substitute the values in the formula


![scale \ factor=\sqrt[3]{8} \\ scale \ factor= 2](https://tex.z-dn.net/?f=%20scale%20%5C%20%20factor%3D%5Csqrt%5B3%5D%7B8%7D%20%5C%5C%20%20scale%20%5C%20%20factor%3D%202%20%20)
<u>Find the surface area of the smaller solid</u>
we know that



substitute the values


therefore
<u>the answer is</u>
The surface area of the smaller solid is equal to 
Answer:
a=25
angle abq=139 degrees
bcr=41
Step-by-step explanation:
(2a-9)+(5a+14)=180
7a+5=180
7a=175
a=25
2(25)-9=41
180-41=139
angle abq=139 degrees
bcr=41
Using m = (y2-y1)/(x2-x1)
(2-3)/(4-2)
-1/2
The slope is -1/2. b.
