OpenStudy (soprano.h.d0816):

Okay(:

Which could be the measures of the three angles of an acute triangle? A. 30°, 30°, 120° B. 30°, 60°, 90° C. 50°, 55°, 75° D. 40°, 40°, 100°

OpenStudy (soprano.h.d0816):

An acute triangle is a triangle with all three angles acute (less than 90°). An obtuse triangle is one with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180°, no triangle can have more than one obtuse angle.

OpenStudy (richgall____):

Acute triangles normally have angles lower than 90 degrees ( that should give you a clue)

OpenStudy (richgall____):

you type fats ^^

OpenStudy (richgall____):

*fast

OpenStudy (soprano.h.d0816):

But, if it contains a 90 degree angle, it is a right triangle

OpenStudy (soprano.h.d0816):

I really hope this helps(:

OpenStudy (anonymous):

so c?

OpenStudy (soprano.h.d0816):

Correct!!

OpenStudy (soprano.h.d0816):

Add 40 and 40 together and then subtract from 180

OpenStudy (anonymous):

100

OpenStudy (soprano.h.d0816):

Correct!!

OpenStudy (anonymous):

I have 2 more questions

OpenStudy (soprano.h.d0816):

Give em(:

OpenStudy (anonymous):

OpenStudy (soprano.h.d0816):

Same thing here. Add 56 and 36 then subtract from 180

OpenStudy (anonymous):

-88?

OpenStudy (soprano.h.d0816):

Not negative.

OpenStudy (anonymous):

so just 88

OpenStudy (soprano.h.d0816):

56 + 36 = 92 180 - 92 = 88 Yes

OpenStudy (anonymous):

OpenStudy (soprano.h.d0816):

Add 44 and 66

OpenStudy (anonymous):

110

OpenStudy (soprano.h.d0816):

Now, subtract 110 from 180. It should be positive
