M<AVC = 43 degrees, because it is the angle's measure is 1/2 of the arc's
Answer:
6000 square millimeters
Step-by-step explanation:
Side length of the slanting side can be calculated using the Pythagorean theorem,
L = sqrt(30^2+40^2) = 50
sufrace area of a triangular prism
= surface area of the end sections + the surface area of the three side faces
= 2*(30*40/2) + 40*(30+40+50)
= 1200 + 4800
= 6000 mm^2
70/81 is 7/81+7/9 as a proper fraction
The discriminant is b²-4ac
when the discriminant is 0, there is only one solution.
