Asked by A dude who needs help with math

To answer these questions just pick the letter format or say the numbers. Two adjacent angles are on a straight line. One angle is (5x−28)° and the other angle is 8x°. What is the degree value of the second angle? Choses to pick from are
A 120
B 52
C 16
D 128

For two adjacent angles x° and (x+30)° that make up a 90° angle, what is x?
Is it 60?

Answered by Tammy
The bot is wrong again in math.




The two angles are on a straight line, so their sum is 180° , not 90°
so we would have :
5x-28 + 8x = 180
13x = 208
x = 16

so the second angle is 8x or 128°

The bot gets about one out of five right.

Yes, x is equal to 60.
