The triangle sum theorem says all 3 interior angles must equal 180 degrees.
so, 43 + 35 = 78. [ 180 - 78 = 102 degrees for the missing angles shared by the 2 triangles.
102 + 18 = 120. [180 - 120 = 60}
leaving the measure of Angle A as 60 degrees.
Step-by-step explanation:
288÷60(60 minutes in an hour) = 4.8

Answer:
43.638 cubic meters
Step-by-step explanation:
The triangular prism has 5 faces - 3 rectangular and 2 congruent triangular. Calculate the area of each face then add them together to find the surface area.
The triangles are 5.3 by 1.26 so the area of the two is 6.678.
The largest rectangle face is 5.3 by 3.3 so the area is 5.3*3.3 = 17.49.
The side rectangle face that is 3.3 by 3.6 so the area is 3.3*3.6 = 11.88.
The side rectangle face that is 2.3 by 3.3 so the area is 2.3*3.3 = 7.59.
Add all the areas together.
6.678 + 17.49 + 11.88 + 7.59 = 43. 638
