Can you put copies of an equilateral triangle together to form a right angle

No.

90° is not a multiple of 60°.

no

Step-by-step explanation:

i dont think so

90° is not a multiple of 60°

A symmetrical triangle can not be a correct triangle. This bodes well in light of the fact that the point gauges in any triangle, not just a symmetrical triangle, equivalent 180 degrees. In a correct triangle, be that as it may, the 3 edges can NOT be consistent. This is on the grounds that in a correct triangle, one edge rises to 90 degrees.

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

no this is a nonlinear negative
