- [Right Triangles Only]: Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use PT to solve for the missing length.
<u>Step 2: Identify Variables</u>
Leg <em>a</em> = 8
Leg <em>b</em> = 8
Hypotenuse <em>c</em> = <em>x</em>
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute [PT]: 8² + 8² = x²
- Exponents: 64 + 64 = x²
- Add: 128 = x²
- Isolate <em>x</em>: 8√2 = x
- Rewrite: x = 8√2
To get the circumference you times 3.14 which is PI and times PI by diameter to get the circumference
Answer:
9811
Step-by-step explanation:
Because of the exterior angle theorem, 2x + 70 = 4x so to find the x do this equation ... so x would equal 35 degrees and the question is asking for m< XYZ which is 2x and substitute for x so 2(35) is 70 degrees. M
