$\\ \bull\tt\dashrightarrow BC=CE$

$\\ \bull\tt\dashrightarrow 3x+3y=7x+5y$

$\\ \bull\tt\dashrightarrow 7x-3x=3y-5y$

$\\ \bull\tt\dashrightarrow 4x=-2y$

$\\ \bull\tt\dashrightarrow 2x=-y$

$\\ \bull\tt\dashrightarrow \dfrac{x}{y}=\dfrac{-1}{2}$

Now

$\\ \bull\tt\dashrightarrow BE=BC+CE+CD$

$\\ \bull\tt\dashrightarrow BE=3x+3y+7x+5y+5x-2y+6$

$\\ \bull\tt\dashrightarrow BE=15x+6y+6$

A tomato plant grew an average of 0.06 m per day. how many days did it take for the plant to grow a total of 0.96 m?

gizmo_the_mogwai [7]

1 day = 0.06 m
x = 0.96 m

0.96 ÷ 0.06 = 16 days

(someone please answer these. im literally not turning in my test until someone does. ) 1 a ladder is leaning agisnt a building

dezoksy [38]

Answer:

1. 15ft

2. 12

Step-by-step explanation:

1. See the attachment below showing the right triangle formed by the ladder and the building.

Let x represent how far the roof line is from the ground.

Thus, using Pythagorean Theorem, x can be solved as follows:

x² = 17² - 8²

x² = 225

x = √225

x = 15ft

2. Given:

Reference angle = 45°

x = Hyp

6√2 = opposite

Using trigonometric ratios formula, thus:

$sin(45) = \frac{6\sqrt{2}}{x}$

Multiply both sides by x

$sin(45)*x = 6\sqrt{2}$

Divide both sides by sin(45)

$x = \frac{6\sqrt{2}}{sin(45)}$

$x = \frac{6\sqrt{2}}{\frac{1}{\sqrt{2}}}$ (common value of sin(45) = 1/√2)

$x = 6\sqrt{2} \times \frac{\sqrt{2}}{1}$

$x = 6\sqrt{2 \times 2}$

$x = 6 \times 2$

$x = 12$
