Answer:
Step-by-step explanation:
2 x 4 = 8
3 x 5 = 15
8/15
If the angle is mesure in RADIANS then the arc is given by r. So first convert 81 degrees to radians, then multiply by r which is 10 x 81=810
Answer:
It would be 4:6
Step-by-step explanation:
2*2=4
3*2=6
they both multiply by 2
hopefully that makes sense.
Answer:
In the case of the equilateral triangle, , the exterior angle, plus 60 equals 180. Subtracting 60 from both sides of this equation gives us a value of equal to 120. This means that the exterior angle of an equilateral triangle is equal to 120 degrees. The sum of all the exterior angles is always 360 degrees.
