Can someone please explain?
geniusboy [140]

This is an isosceles triangle. The angles at the base are congruent (they have the same measures).

Look at the picture.

We know: The sum of the measures of angles in a triangle is equal 180°.

Therefore we have the equation:

2x-10+2x-10+3x+25=180       <em>combine like terms</em>

(2x+2x+3x)+(-10-10+25)=180

7x+5=180           <em>subtract 5 from both sides</em>

7x=175              <em>divide both sides by 7</em>

x=25

m\angle A=2x-10\to m\angle A=2(25)-10=50-10=40\\\\m\angle C=m\angle A=40\\\\m\angle B=3x+25\to m\angle B=3(25)+25=75+25=100^o

<h3>Answer: D. m∠C = 40</h3>

Sandra saves 12% of her salary for retirement. This year her salary was $3,000 more than in the previous year, and she saved $4,
slava [35]
So since we know she saved 12% in the previous year so you would make a graph and then draw 100 squares now since 12 dosen't go into 100 evenly you would multiply 12 until you get 96% (which is multiplying 12 by 8) then her salary would be $4,200 dollars multiplied by 8 which is 33,600 dollars then to get your 4 more percent you would divide 12 by 3 which is 4 and you would also divide 4,200 by 3 which is 1,400 and add that to 33,600 dollars and her salary would be 35,000 dollars in the previous year her current year salary would be 38,000 dollars.
