\mathsf\red{♧ANSWER♧}

\mathsf \blue{5 \frac{2}{5}  - 3 \frac{7}{10} }

\blue \implies \mathsf \green{ \frac{27}{5}  -  \frac{37}{10} }

\blue \implies \mathsf \green{2( \frac{27}{5} ) -  \frac{37}{10} }

\blue \implies \mathsf \green{ \frac{54}{10}  -  \frac{37}{10} }

\blue \implies \mathsf \green{ \frac{17}{10}  = 1  \frac{7}{10}  = 1.7}

What is measure of angle A?
Goryan [66]

Answer:

A=53.13\°

Step-by-step explanation:

The figure shows a right triangle.

To calculate the measure of the angle A, you can use the inverse trigonometric function arctangent:

\alpha=arctan(\frac{opposite}{adjacent})

Identify the angle \alpha, the opposite side and the adjacent side:

\alpha=A\\opposite=4cm\\adjacent=3cm

Substitute into \alpha=arctan(\frac{opposite}{adjacent}).

The measure of the angle A is:

A=arctan(\frac{4}{3})\\\\A=53.130\°

Rounded to the nerarest hundreth:

A=53.13\°

<h3>Answer:   7 goes in the blank space</h3>

The range of values for x is 2 < x < 7

========================================

Explanation:

The hinge theorem says that the larger the opposite side is, the larger the angle will be.

AD = 11, DC = 8

Since AD > DC, this means angle ABD > angle DBC.

--------

angle ABD > angle DBC

20 > 4x-8

20+8 > 4x-8+8 ... add 8 to both sides

28 > 4x

4x < 28 ... flip both sides and the inequality sign

4x/4 < 28/4 ... divide both sides by 4

x < 7

--------

At the same time, the angle 4x-8 cannot be 0 or negative.

So we say 4x-8 > 0. Let's solve this for x.

4x-8 > 0

4x-8+8 > 0+8 ... add 8 to both sides

4x > 8

4x/4 > 8/4 ... divide both sides by 4

x > 2

2 < x ... flip both sides and the inequality sign

--------

We have 2 < x and x < 7. Both of these combine to the compound inequality 2 < x < 7

We can pick any value between 2 and 7 as long as we dont pick x = 2 or we dont pick x = 7.
