for number 1, i got b
OpenStudy (yanasidlinskiy):
Hello Alina! Do you know what complementary angles are at first?
OpenStudy (alina123):
i think their sum of their angles measure 90 degrees
OpenStudy (yanasidlinskiy):
Yep! correct! Since, a straight line equals 180 degrees....Which one =90?

You want help with #2 also.Correct?
OpenStudy (alina123):
yes
OpenStudy (yanasidlinskiy):
Look carefully @ those angles that they ask to give the measure of. Tell me what kind of triangle is it? How much degrees does it measure?
OpenStudy (alina123):
a reflex that is greater than 180 degrees
OpenStudy (yanasidlinskiy):
No. In other words the angle is obtuse. How much degrees do these angles measure? Remember that a straight line = 180 degrees!

greater than 90 but less than 180
OpenStudy (yanasidlinskiy):
Yes. So this question is common sense. Which answer is it from the choices?
OpenStudy (alina123):
b
OpenStudy (yanasidlinskiy):
Hint: Right triangles= 90
Obtuse = 130
Isosceles = 180
OpenStudy (yanasidlinskiy):
Look at the hints above that I gave you above. If it's obtuse it is??........

jigglypuff314 (jigglypuff314):
I gtg eat dinner

http://prntscr.com/3ayogp
so 90 + x + 55 + 2x - 49 = 180 solve for x :)
OpenStudy (alina123):
oh ok
