The measure of angle D is 39 degrees.

Since it’s an isosceles triangle, the two unmarked angles are equal. Since you know there are 180° in a triangle, subtract 102° from 180° to get 78°. Then, cut that in half since you need to divide it equally among the two remaining angles.

Answer:

$\large\boxed{V=\dfrac{49\pi}{3}\ in^3}\approx51.29\ in^3}$

Step-by-step explanation:

The formula of a volume of a cone:

$V=\dfrac{1}{3}\pi r^2H$

r - radius

H - height

We have

r = (7 : 2) in = 3.5 in

H = 4 in

Substitute:

$V=\dfrac{1}{3}\pi(3.5)^2(4)=\dfrac{1}{3}\pi(12.25)(4)=\dfrac{49\pi}{3}\ in^3$

$\pi\approx3.14\\\\V\approx\dfrac{(49)(3.14)}{3}\approx51.29\ in^3$

Hi there!

I believe your answer is:

"Add 4 to both sides, and then divide by 2. The solution is x = 12."

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

To solve for 'x', we would have to use inverse operations.
We would first have to add four to both sides to undo the negative four. Addition is the opposite of subtraction.
We would then divide by 2 to isolate 'x'. Division is the opposite of multiplication.

⸻⸻⸻⸻

$\boxed{\text{Solving for 'x'...}}\\\\2x - 4 = 20\\------------\\\rightarrow 2x - 4 + 4 = 20 + 4\\\\\rightarrow 2x = 24\\\\\rightarrow \frac{2x=24}{2}\\\\\rightarrow \boxed{x = 12}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
