The measures of two of the sides of an equilateral triangle are 3x + 15 in. and 7x – 5 in. What is the measure of the third side in inches?
For anyone that has the quick check, these may not be the same for everyone but these were what the correct answers were for me
1. C
2. A
3. D
4. A
5. B
Hope this helps!! :) -Pico
Ms. Sue is wrong.
equilateral triangle means all the sides are the same.
x=5 yes but you have the x's with the five and then solve the equation so it will be this.
3(5)+15=30
7(5)-5=30
now that you know these sides equal 30 the third side equals 30 as well be it is an equilateral triangle.
1.) line FD is congruent to Line ED
2.) 14
3.) 30
4.) 28.5*
5.)vertex
GoPico is correct
Ya gotta watch out for Ms. Sue; she's a sly one. Notice how she solved for x, but she left it up to to actually answer the question!
