Answer:

The answer is:

B) 66 degrees

Step-by-step explanation:

Since the triangle is an isosceles triangle, angle C is the same as angle B.

57 + 57 = 114

Since you know two of the three angles, and you know that a triangle's angles must equal 180 degrees...

180 - 114 = 66

Angle A must equal 66 degrees for the triangle to equal 180 degrees.

I hoped this helped you! If it did, please consider rating and pressing the 'Thanks' button. Have great day!

Which of the following is the solution set for the conjunction –6 < 4x + 2 < 6? x>−32 and x<32 x >–2 and x < 1
alisha [4.7K]

-6

<em><u>Solution:</u></em>

<em><u>Given conjunction is:</u></em>

-6

We have to find the solution set

<em><u>Let us solve the given conjuction</u></em>

\mathrm{If}\:a

Therefore,

-6

<h3><em><u>Let us first solve -6 < 4x + 2</u></em></h3>

-6 < 4x + 2

Switch the sides by flipping the inequality symbol

4x+2>-6

\mathrm{Subtract\:}2\mathrm{\:from\:both\:sides}\\\\4x+2-2>-6-2\\\\\mathrm{Simplify}\\\\4x>-8\\\\\mathrm{Divide\:both\:sides\:by\:}4\\\\\frac{4x}{4}>\frac{-8}{4}

x>-2

<h3><u><em>Now let us solve 4x + 2 < 6</em></u></h3>

4x+2

\mathrm{Combine\:the\:intervals}

x>-2\quad \mathrm{and}\quad \:x

Merge\:Overlapping\:Intervals

-2

<h3><u>Thus the solution set for  –6 < 4x + 2 < 6 is:</u></h3>

-6
