Answer:

x = 4 $\sqrt{2}$

Step-by-step explanation:

note the exact value of tan60° = $\sqrt{3}$

Since the triangle is right use the tangent ratio to find x

tan60° = $\frac{opposite}{adjacent}$ = $\frac{4\sqrt{6} }{x}$

multiply both sides by x

x × $\sqrt{3}$ = 4 $\sqrt{6}$

divide both sides by $\sqrt{3}$

x = $\frac{4\sqrt{6} }{\sqrt{3} }$ = 4 × $\sqrt{\frac{6}{3} }$ = 4 $\sqrt{2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -3.75)

Point (-1, 4.5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1--1)^2+(4.5--3.75)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(0)^2+(8.25)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{0+68.0625}$
[√Radical] Add: $\displaystyle d = \sqrt{68.0625}$
[√Radical] Evaluate: $\displaystyle d = 8.25$
