Wow. Let's start with 2. What is the sum of the measures of the angles of a triangle?

2 years ago
OpenStudy (anonymous):

38 71 and x

OpenStudy (mathstudent55):

I don't mean the triangle in the problem. In any triangle, what is the sum of its measures?

OpenStudy (capnkookcx):

Just do this 38 + 71 then minus the sum by 180 and you got your answer. :)

Just do the same 45 + 45 then subtract the sum by 180. :)

:) ok

180

OpenStudy (mathstudent55):

No. You need to do 180 - 45 - 45

A right isosceles triangle had a right angle of 90 degrees. The other two angles' measures add up to 90 degrees. Since the other two angles are congruent, they each measure 45 degrees.

sooo 45?

2 years ago
OpenStudy (mathstudent55):

The wording of problem 3 is not good, because there are two angles we were not told the measures of, so we don't know which one the problem means when it asks for the measure of the "third angle." It could the the 90-deg angle or the 45-deg angle.

@mathstudent55 ?

OpenStudy (mathstudent55):

Since there is no choice of 90 deg, it must be the 45-deg angle, but if this were not multiple choice, I would not have known it.

2 years ago
OpenStudy (mathstudent55):

Yes, 45 deg.

Now problem 4. @ZinnaPinkerton We need to know this: What is the sum of the measures of the angles of any triangle?

2 years ago
OpenStudy (anonymous):

ok 4... sorry there are so many questions

OpenStudy (anonymous):

180 right?
