Answer:
20mm
Since it a equilateral triangle we know that there is 3 sides and all of them are euqal. Therefore, 60/3 =20 meaning each side is 20mm.
Answer:
the slope is 3 you are right
Step-by-step explanation:
y=mx+b
where m is the slope.
Answer:
x = 59
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
x + 3 + x + x = 180
3x + 3 = 180 ( subtract 3 from both sides )
3x = 177 ( divide both sides by 3 )
x = 59
