What is m∠ACB 90° 48° 84° 96°

OpenStudy (anonymous):

OpenStudy (anonymous):

This is easy ^_^ do you know what a right angle is and how much the degree is? it's 90 degrees

OpenStudy (anonymous):

and the angle is bigger meaning A B and C are wrong ^_^

OpenStudy (alexandervonhumboldt2):

just add the measurments of 2 given to you adjacent angles

OpenStudy (anonymous):

so answer D is correct

OpenStudy (alexandervonhumboldt2):

add <ACD+<DCB=24+72=???

OpenStudy (anonymous):

also you can also do 24 + 72 = 96 < also my answer ^_^

Thank you for the medal btw ^_^ <3

The Angle Addition Postulate m<1 + m<2 = m<ABC |dw:1443806629593:dw|

^ nice explanation math student ^_^ ~medals~

OpenStudy (mathstudent55):

@Captain_America_Army You got the right answer, D, but I don't know why you mentioned right angles, since there is no right angle in this problem.

OpenStudy (anonymous):

Ik ^_^ but I like referring to it, As I know its a strait angle that looks like a capital "L" and that was a little more than a straight "L"

OpenStudy (anonymous):

as we know the right angle is 90 degrees and the only answer choice more than 90 degrees was choice D

OpenStudy (mathstudent55):

I see. That's a good point. Thanks for the explanation. You need to be careful with geometry problems, though. Very often books tell you that the figures are not drawn to scale, so you should not go by what the figure looks like. You can only go by the information given, such as angles measures. They do this on purpose. The reason is that they want you to calculate the angle measure, not to use a protractor to measure it.

Ok thank you
