Need help ASAP. The diagram shows 5ft student standing near a tree. The shadow of the student and the shadow of the tree at endp

inna [77]

Answer:

The height of the tree = 25 feet

Step-by-step explanation:

From the given diagram : EF = 5 feet, FA = 8 feet, CA = 40 feet

∠AFE = 90° and ∠ACB = 90°

To find : CB, the height of the tree.

Solution : In ΔAEF and ΔAB C

∠AFE = ∠ACB = 90°

∠A is common angle.

So, By AA postulate of similarity of triangle, ΔAEF ~ ΔABC

Now, sides of similar triangles are proportional to each other

$\implies\frac{FA}{CA}=\frac{EF}{CB}\\\\\implies \frac{8}{40}=\frac{5}{CB}\\\\\implies CB=\frac{40\times 5}{8}\\\\\implies CB=25$

Hence, The height of the tree = 25 feet

Work out the angle of size x

zzz [600]

Answer:

x=75

Step-by-step explanation:

$We\ are\ given\ that, \\Angle GFE=105\\We\ observe\ that, \\Angle\ GFE\ and Angle\ EFB\ form\ a\ linear\ pair\ and\ hence,\ are\ supplementary.\\Hence,\\Angle\ GFE\ + Angle\ EFB=180\\Hence,\\105+Angle\ EFB=180\\Angle\ EFB=180-105\\Angle\ EFB=75\\We\ know\ observe\ that\ Angle\ EFB\ and\ Angle\ ABC\ are\ corresponding\ angles\ and\ are\ equal\\Hence,\\Angle\ EFB\ = \ Angle\ ABC\\75=Angle\ ABC\\75=x\\x=75$

What is T In the equation 3/7+t=20/21

stealth61 [152]

Answer:

$\large\boxed{t=\dfrac{11}{21}}$

Step-by-step explanation:

$\dfrac{3}{7}+t=\dfrac{20}{21}\qquad\text{subtract}\ \dfrac{3}{7}\ \text{from both sides}\\\\\dfrac{3}{7}-\dfrac{3}{7}+t=\dfrac{20}{21}-\dfrac{3}{7}\qquad\text{LCD(7, 21)=21}\\\\t=\dfrac{20}{21}-\dfrac{3\cdot3}{7\cdot3}\\\\t=\dfrac{20}{21}-\dfrac{9}{21}\\\\t=\dfrac{20-9}{21}\\\\t=\dfrac{11}{21}$
