Answer: No, it is not possible
A triangle can only have 1 obtuse interior angle, leaving the exterior angle next to it to be acute. For example, if you have an interior angle of 120 (obtuse) then the adjacent exterior angle is 60 (acute)
The other two interior angles must be acute if you go with 1 obtuse angle, which leaves the corresponding exterior angles to be obtuse. If you wanted the exterior angles to be all acute, then you would need 3 obtuse interior angles, but that is not possible.
Why isn't it possible to have 3 obtuse angles? Consider a triangle with interior angles A, B, C. The three angles must add to 180
A+B+C = 180
If A,B,C were all larger than 90, then
A > 90
B > 90
C > 90
A+B+C > 90+90+90
A+B+C > 270
but that contradicts A+B+C being equal to 180
Answer:
4° C per hour
Step-by-step explanation:
16/4 will give us the temperature change every hour
9:45 plus 3 hours goes to 12:45 pm. add 45 minutes you get 1:30PM as your answet
Answer:
To convert from degree to radian we multiply the angle by
π/180
To convert from radian to degree we multiply the angle by
180/π
5π/6,
Multiply by
180/π
=
5π/6 × 180/π = 5 × 30 = 150 degrees.
⇒5π/6 radian =150 degree.
