Step-by-step explanation:

The objective is to find the missing angles.

It is given that <DOE = 53° and <AOF = 51°.

Then, the angle b can be calculated by the angel sum property of triangle as,

<AOF + <<em>b</em> + <DOE = 180⁰

51⁰ + <em>b</em> + 53⁰ = 180⁰

<em>b</em> + 104⁰ = 180⁰

<em>b</em><em> </em>= 180⁰ - 104⁰

<em>b</em><em> </em><em>=</em><em> </em><em>7</em><em>6</em><em>⁰</em>

<em>From figure, line BE and AD are intersecting lines. Then, by the property of vertically opposite angles,</em>

<em><</em><em>b</em><em> </em>= <<em>d</em>

<em><</em><em>d</em><em> </em>= 76⁰

From figure, line BE and AD are intersecting lines. Then, by the property of vertically opposite angles,

<<em>a</em><em> </em>= <AOF

<<em>a</em><em> </em>= 51⁰

What is the solution to 3(x + 8) &gt; 2 (2x + 10)?<br> 4<br> O<br> 0<br> (-4, 6)<br> (-5, 4)
Deffense [45]

Answer:

x<4

Step-by-step explanation:

For this inequation:

3(x + 8) > 2 (2x + 10)

or 3x +24 > 4x +20

-4x+ 3x + 24> -4x +4x +20

and we have -x +24> 20

or -x +24 -24 > 20-24

-x >-4 and finally x < 4 ( multiple -1 for both sides, > change into <)

All real number x so that x< 4 is solution.

Have a good day.
