Answer:
2 cm, 9 cm, 10 cm
Step-by-step explanation:
To know if a combination is a triangle all you have to do is see if the combinations add up to 180
(2)(9)(10)=180 therefore it is a triangle.
All the other angles do not add up to 180 so they can't be triangles!!
(4)(10)(3)
=120
(5)(6)(11)
=330
(4)(5)(7)
=140
Answer: -16
Step-by-step explanation:
-3 is less than -2 so use the first one
Plug into equation
5(-3)-1
-15-1= -16
Combine the fractions by finding a common denominator.
10r+9/r(r+3)
X = 36
because angle 108 = 3x
3 x 36 = 108
hope it makes sense, if you have any questions let me know
