- Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 64
Hypotenuse <em>c</em> = 80
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: x² + 64² = 80²
- Isolate <em>x</em> term: x² = 80² - 64²
- Exponents: x² = 6400 - 4096
- Subtract: x² = 2304
- Isolate <em>x</em>: x = √2304
- Evaluate: x = 48
Answer:-5
Step-by-step explanation:
2x+3=-7
2x=-7-3
x=-10/2
so,
x=-5
