Question

Solve for x Please help

Answer 1

Answer:

3. A; 4. C; 5. D; 6. D

Step-by-step explanation:

3. By Pythagorean theorem, x^2=100-64=36, x=6

4. By Pythagorean theorem, x^2=81-36=25, x=5

5. Since the triangle is an isosceles, the other side is 4, so the hypotenuse is 4$\sqrt{2}$. (the ratio is 1:1:$\sqrt{2}$ by Pythagorean theorem)

6. Like Question #5, the ratio is 1:1:$\sqrt{2}$ since it is an isosceles triangle, the leg is 8.
