If m∠A = (11x + 37)° and x = 13, find m∠A and classify the angle (acute, right, obtuse, straight). Someone give me the two answers for this problem.

9514 1404 393

  obtuse, straight

Step-by-step explanation:

If you insist on two answers, there is only one pair of answers that are self-consistent:

  obtuse, straight

__

m∠A = (11(13) +37)° = (143 +37)° = 180° . . . . a straight angle, also obtuse

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

it would rotate about 180 degrees.
