Answer: 96 ft squared ✌️

Step-by-step explanation:

Triangle area is 42 a leg (6) times b leg (14) divided by 2

First rectangle down is 30. Use length times width

Second rectangle down is 14

Last vertical rectangle is 10

Add all areas together

Answer: 96 square feet.

Step-by-step explanation: I would assume you know how to find the area of the rectangles and you are struggling with the triangle. With triangles you take the base or the bottom and multiple it by the width and then divide by 2. In this case the base would be 14 and the width would be 6, so 14x6 is 84 and 84 divided by 2 is 42.

I am guessing you are in 6th grade based on the problem you are doing. I am also in 6th grade so try to do what I did and see for yourself. :)

4 cot theta = tan theta how do I I find the value of quadrant?

Ray Of Light [21]

Answer:

4cotα=tanα

4(1/tanα)=tanα

(4/tanα)=tanα

cross multiply

=> 4=tan²α

√4=√tan²α

±2=tanα

α=arc( tan) |2|

α=63.4° ( in first quadrant)

and

α=180+63.4=243.4 in the third quadrant

since we also found a negative answer( i.e –2) then α also lies in quadrants where it gives a negative value(i.e second and fourth quadrants)

α=180–63.4=116.6° in the second quadrant

α=360–63.4=296.6 in the fourth quadrant

therefore theta( in my case, alpha) lies in all four quadrants and is equal to:

α=63.4°,243.4°,116.6°and 296.6°

The hypotenuse of a right triangle is 6 inches. if one of the legs is 2 inches, find the degree measure of each angle

miskamm [114]

A and b are the 2 smaller sides, and c = hypotenus; only for right triangles,
Pythagorean Theorem states that:
${c}^{2} = {a}^{2} + {b}^{2}$
given c = 6 in., a = 2 in.
${c}^{2} = {a}^{2} + {b}^{2} \\ {6}^{2} = {2}^{2} + {b}^{2} \\ {b}^{2} = {6}^{2} - {2}^{2} = 36 - 4 \\ \sqrt{ {b}^{2} } = \sqrt{36 - 4} = \sqrt{32}$
$b = \sqrt{32} = \sqrt{16} \times \sqrt{2} = 4 \sqrt{2} \\ b = 5.66 \: inches$
So the three side are 2, 6, and 5.66 inches

A placebo is a substance that should elicit no positive response in an experimental subject.

adelina 88 [10]

Answer:

A) True

Step-by-step explanation:

In an experiment that has the purpose of testing the efficacy of a procedure or drug, comparison is made against the efficacy of a placebo, a procedure or drug that is intended to have no effect whatever.

Famously, a placebo is often found to be nearly as effective (or even more effective) than the procedure or drug on trial. This effect is known as "the placebo effect."

Write a linear equation in slope-intercept form: 5y – 3x + 20 = 0

Arturiano [62]

Slope intercept form is y = mx+ b

So in order to turn 5y-3x + 20 = 0 into Slope intercept form, all we need to do is solve for y!

Let's do it!

add 3x to the right side of the equation

5y - 3x + 20 = 0

5y + 20 = 3x

move 20 to the right side

5y = 3x - 20

Divide both sides of the equation by 5

y = 3/5x - 4

This is our answer!

I hope I helped! Leave a comment if you have any questions or concerns
