- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
3x + 3x + 10 + 2x + 10 = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 8x + 20 = 180
- Isolate <em>x</em> term: 8x = 160
- Isolate <em>x</em>: x = 20
It will take the same as the left then on the right 18lb

Hey!
There probably is a reason she is deleting. You could contact her or ask some help elsewhere.
Anyway! I'm trying to get this in fast. (Remember the Pythagorean Theorem?) That will be very useful here since it is a right triangle.
<u>L² + L² = H² (or H² - L² = L²):</u>
In that case, we'll use the second one because our Hypotenuse is given.
We can substitute each value of the numbers:
65² - 60² = L²
Evaluating:
4225 - 3600 = 625
√625 = 25 inches
Thusly, the third side would be
<em>Also note we could have simplified into a Pythagorean Triple. This method is a simpler more basic method for learning the concept.</em>
Hope this helps!
Answer:
5:3
Step-by-step explanation:
to simplify this equation we have to find something that both numbers can be divided by
both numbers can be divided by 7
so when we divide the numbers we get
5b = 3c
so basically the ratio is 5:3
