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.
The other end-point is: (2,6)
Step-by-step explanation:
Let the end-points be:

(x1,y1) = (10,12)
Mid-point = M = (6,9)
The formula for mid-point is given by:

Putting the values

Putting respective coordinates equal

The other end-point is: (2,6)

Answer:
B. 32 square inches
Step-by-step explanation:
Each of the two triangular faces has an area of ...
A = (1/2)bh = (1//2)(6 in)(4 in) = 12 in²
The lateral surface area is the product of the prism height (0.5 in) and the perimeter of the base.
LA = (0.5 in)(5 in +5 in + 6 in) = 8 in²
So, the total area is the area of the two base and the lateral area:
SA = 2A +LA
SA = 2(12 in²) +8 in² = 32 in²
The surface area of the prism is 32 square inches.
