Can you solve this problem:
Identify the letter of the choice that best completes the statment or answer the question.
Note: Since there is no symbol on the keyboard for the right angle sign I will use the greater than sign(<)right angle. The greather/less than sign for the (<>)for a triangle symbol.
m<A=9x-7,m<B=7x-9,and m<C=28-2x. List the sides of <>ABC in order from shortest to longest.
Answers: a. AB;AC;BC b. BC;AB;AC
c. AC;AB;BC d. AB;BC;AC
You know the angles add to 180
so add them up and solve for x.
9x-7 + 7x-9 + 28-2x=180
solve for x.
That will give you the angles. Then, the longest side is opposite the larger angle, and so on.
i got x=11 but the sum of the sides equal 166 and not 180 what did i do wrong??
