Answer:

Step-by-step explanation:

$A_1 = a^2 = 14^2 = 196$

$A_2 = 4(\frac{b * h}{2}) = 4(\frac{14 * 12}{2}) = 4(\frac{168}{2}) = 4 * 84 = 336$

$SA = A_1 + A_2 = 196 + 336 = 532\ cm^2$

What is the equation of the line that passes through the point (-6,-2)and has a slope of 1/6

balu736 [363]

Answer:

y = 1/6x -1

Step-by-step explanation:

Use point-slope form: y - y₁ = m (x - x₁)

y - (-2) = 1/6 (x - (-6))

y + 2 = 1/6x + 1

y = 1/6x - 1

For which acute angles is the following statement true? The complement of the angle is smaller in measure than either of the two

Hitman42 [59]

Let the acute angle be 2x.

Its complement is 90 - 2x.

It is given that this complementary angle is less than each of the bisected angle.

Therefore, 90 - 2x < x

90 < 3x

or, x > 30.

2x > 60

Therefore, the statement is true for all angles that are greater than 60 degrees.

GEOMETRY! The diagram shows 5 ft student standing near a tree. The shadow of the student and the shadow of the tree end at point

yuradex [85]

Answer: 24.99 ft

Step-by-step explanation:

1. You can find the angle A as following:

$A=arctan(\frac{5}{8})\\A=32\°$

2. Now, you can calculate the height of the tree as following:

$tan(A)=\frac{opposite}{adjacent}$

Where:

A=32°

opposite=x

adjacent=40

3. When you substitute values and solve for x, you obtain that the height of the tree in feet is:

$tan(A)=\frac{x}{40}\\x=40*tan(32\°)\\x=24.99$
