Hello! To solve this, we will be using Pythagorean Theorem multiple times in order to find AC.
The formula that we will be using is c=sqrt(a^2+b^2) (A and B both being the legs and C being the hypotenuse of the triangle.)
First we need to figure out the measurement of AD, and we know that AB (which AD lies within) is 21, but that's the measurement for the entire leg, what is it for the separate triangles? Well, we'll use the measurements from the right-side triangle to find what B is (you switch up the formula and turn it into b=sqrt(c^2-a^2) )
The measurement of our hypotenuse is 17 (CB) and our leg for A is 8 (CD), so by plugging these measurements in, we see that our other leg is 15.
Now we're almost done. We subtract 15 from 21 (21 - 15) to get what the left-side triangle equals and we get 6. And since CD is shared by both triangles, we use the original formula to solve for the hypotenuse.
When you plug everything in, you'll see that the answer is 10.
AC is 10
Your equation is 0.6g=-7. You are trying to get the value of the variable, G, so you need to isolate it. To do this, you need to get rid of 0.6! Since it is being multiplied by g, you will divide it on both sides to undo the operation. Take 0.6 and say 0.6g/0.6 which will give you g. Now, do the same on the other side of the equal sign and say -7/0.6, which I get -11.666... (-11.6 repeating, or 'bar'-11.6 which you will write as -11.6 with a line drawn over it. If you need it in a fraction, most calculators should have an option to convert it, or you can do it yourself if you know how).

The answer is 33.6. Hope that's what your looking for.
Answer:
w = 4
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
13w + 18w + 56 = 180
31w + 56 = 180 ( subtract 56 from both sides )
31w = 124 ( divide both sides by 31 )
w = 4
