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

no   i hope this helps!   :)

Step-by-step explanation:

90° is not a multiple of 60°

i dont think so

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 simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
