Answer the following question

FromTheMoon [43]

Answer:

Letters as in the attached image.
Triangles ABC and ADC are congruent by SSS. From that, corresponding angles are congruent, in parcicualre B and D, both measuring 94°.
Final angle is obtained by difference. The internal angles of a quadrilater add to 360, so the remaining is 360-90-94-94 =82°

(Solving for a). b=(4*a)-3/4

Andrei [34K]

Answer:

a = 3/28

Step-by-step explanation:

<em>To start solving for a variable, you need to isolate it.</em>

-4/3b = 4a

<em>-4/3 divided by 4 equals -4/12 or </em><em>-1/3</em>

a = -1/3b

<em>To completely solve for </em><em>a</em><em> we need to plug it back in and solve for </em><em>b</em><em>.</em>

b = (4(-1/3b)) - 3/4

b = -4/3b - 3/4

7/3b = -3/4

b = -9/28

<em>Finally, we can plug </em><em>b</em><em> back in to the previous equation we got for </em><em>a</em><em> to solve for </em><em>a</em><em>.</em>

a = -1/3(-9/28)

a = 3/28

<em>Furthermore, we can check if this is correct by plugging in </em><em>3/28</em><em> for </em><em>a</em><em> into the original problem and see if we get what we got for </em><em>b</em><em> (</em><em>-9/28</em><em>)</em>

A 14 foot ladder is leaning against a building. The ladder makes a 45 degree angle with the building. How far up the building do

IrinaVladis [17]

Answer: $7\sqrt{2}$ feet

Step-by-step explanation:

This question uses special right triangles.

There are two main special triangles to remember.

Attached is a diagram of the triangle. Both the base and the height are the same, so the 14 foot-long ladder is the hypotenuse.

The hypotenuse of a 45-45-90 triangle is equal to $\sqrt{2} *k$ , where k is the side length.

We can solve for the side lengths by using this equation:

$14 = \sqrt{2} *k$

Simplifying this equation by dividing both sides by the square root of 2 and rationalizing the denominator, we get

$7\sqrt{2} =k$

Your side length of the height of the triangle is equal to 7 times the square root of 2.
