Answer:
D
Step-by-step explanation:
The diagram is composed of one large right triangle and inside it it's divided into 2 small right triangles. Since these triangles all have the same shape but not the same size, they are similar triangles. Using similar triangles, create a proportion of side lengths. A proportion is an equation with equal ratios from the large triangle to a small. Notice the large triangle has a hypotenuse of 6+7 = 13 and a leg of x. The small triangle has a hypotenuse of x and a leg of 7.
![\frac{hypotenuse}{leg}=\frac{hypotenuse}{leg}](https://tex.z-dn.net/?f=%5Cfrac%7Bhypotenuse%7D%7Bleg%7D%3D%5Cfrac%7Bhypotenuse%7D%7Bleg%7D)
![\frac{13}{x}=\frac{x}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7Bx%7D%3D%5Cfrac%7Bx%7D%7B7%7D)
To solve for x, cross multiply the numerator with the denominator.
![x*x = 13*7\\x^2 = 91\\x=\sqrt{91} \\x=9.5](https://tex.z-dn.net/?f=x%2Ax%20%3D%2013%2A7%5C%5Cx%5E2%20%3D%2091%5C%5Cx%3D%5Csqrt%7B91%7D%20%5C%5Cx%3D9.5)
