Line segment YV of rectangle YVWX measures 24 units.

Anna [14]

Answer: 8√3

Step-by-step explanation:

ΔXVW is a 30°-60°-90° triangle. This special triangle has corresponding sides of lengths: b - b√3 - 2b. So,

VW = b

XW = b√3

XV = 2b

Since, YV = 24, then XW = 24 and we stated above that XW = b√3. So,

24 = b√3

$\frac{24}{\sqrt{3}} = \frac{b\sqrt{3}}{\sqrt{3}}$

$\frac{24}{\sqrt{3}}$ = b

$\frac{24}{\sqrt{3}}(\frac{\sqrt{3}}{\sqrt{3}})$ = b

$\frac{24\sqrt{3}}{3}$ = b

8√3 = b

We are looking for side YX which is congruent (equal) to VW and we stated above that VW = b, So, VW = 8√3

T/2 + 3 = 5 (solve for t)

Mashutka [201]

Answer:

t = 4

Step-by-step explanation:

Given

$\frac{t}{2}$ + 3 = 5 ( subtract 3 from both sides )

$\frac{t}{2}$ = 2

Multiply both sides by 2 to clear the fraction

t = 2 × 2 = 4
