Answer:

C. x=10

Step-by-step explanation:

Using the Pythagorean Theorem, you know that 7²+s²=(√74)², I'm using the variable s so we don't get confused with the other x variable.

Square root the numbers you can: 49+s²=74

Subtract 49 from both sides of the equation to isolate the variable: s²=25

Square root both sides to find the value of s: s=5

S is half of the value of x, so double s to get your answer, 10

It's an isosceles triangle so the height bisects the base making two right triangles with legs x/2 and y and hypotenuse √74.

(x/2)² + 7² = (√74)²

x²/4 + 49 = 74

x²/4 = 25

x² = 100

x = 10

Answer: C
