Answer:

x = 3

Step-by-step explanation:

In triangle ABC, DE || AC

Therefore by Basic Proportionality Theorem (BPT):

$\frac{x + 5}{2x} = \frac{4}{3} \\ \\ 3(x + 5) = 4 \times 2x \\ \\ 3x + 15 = 8x \\ \\ 15 = 8x - 3x \\ \\ 15 = 5x \\ \\ x = \frac{15}{5} \\ \\ x = 3$

ZP bisects ∠OZQ so that ∠OZP = 8x – 9 and ∠PZQ = 5x + 18. Find the value of x, and the measure of each angle. You must show all

Assoli18 [71]

x = 9 Since ZP bisects â OZQ, that means that the measurements for â OZP and â PZQ are the same. So create an equation with their respective values set to each other. 8x - 9 = 5x + 18 Now solve for x 8x - 9 = 5x + 18 Subtract 5x from both sides 3x - 9 = 18 Add 9 to both sides 3x = 27 Divide both sides by 3 x = 9

Find the value of h in the triangle

sasho [114]

The triangles ABC and ADC are similar.
Therefore
$\dfrac{h}{12}=\dfrac{16}{20}\\\\\dfrac{h}{12}=\dfrac{4}{5}\ \ \ |\cdot12\\\\h=\dfrac{48}{5}\\\\h=9.6\ m$
