In the triangle formed by the statue and the boat, we have

$\tan23^\circ=\dfrac x{110+y}$

and

$\tan38^\circ50'=\dfrac xy$

We can solve either equation for $y$ , then substitute that into the other equation. First, let's abbreviate $t_1=\tan23^\circ$ and $t_2=\tan38^\circ50'$ . Then

$y=\dfrac x{t_2}$

$\implies t_1=\dfrac x{110+\frac x{t_2}}$

$\implies\dfrac{t_1}{t_2}=\dfrac x{110t_2+x}$

$\implies(110t_2+x)\dfrac{t_1}{t_2}=x$

$\implies110t_1=\left(1-\dfrac{t_1}{t_2}\right)x$

$\implies x=\dfrac{110t_1}{1-\frac{t_1}{t_2}}=\dfrac{110t_1t_2}{t_2-t_1}$

$\implies\boxed{x\approx99}$

A biologist uses a box-shaped fish trap that measures 1/4 meter by 2/3 meter by 3/5 meter. What is the volume of the trap in cub

Zolol [24]

To find the volume of a box-shaped fish trap, we have to multiply the three dimensions of it:
(1/4 m)* (2/3 m)* (3/5 m)
= (1*2*3)/ (4*3*5) m^(3)
= 6/ 60 m^(3)
= 1/10 m^(3)
= 0.1 m^(3)

The volume of the box-shaped fish trap is 0.1 m^(3).

Hope this is helpful~

To prove that the triangles are similar by the SAS similarity theorem, it needs to be proven that

Whitepunk [10]

Answer:

I measures 60° ⇒ 3rd answer

Step-by-step explanation:

* Look to the attached figure

- To prove that the two triangles are similar by SAS we must to

find two proportional pairs of corresponding side and the measure

of the including angles between them are equal

- The given is:

m∠ F = 60°

EF = 40 , FG = 20

HI = 20 , IJ = 10

- To prove that the Δ EFG is similar to Δ HIJ we must to prove

# EF/ HI = FG/IJ ⇒ two pairs of sides proportion

# m∠ F = m∠ I ⇒ including angles equal

∵ EF = 40 and HI = 20

∴ EF/HI = 40/20 = 2

∵ FG = 20 and IJ = 10

∴ FG/IJ = 20/10 = 2

∵ EF/HI = FG/IJ = 2

∴ The two pairs of sides are proportion

∵ ∠ F is the including angle between EF and FG

∵ ∠ I is the including angle between HI and IJ

∴ m∠ F must equal m∠ I

∵ m∠ F = 60° ⇒ given

∴ m∠ I = 60°

* I measures 60°
