Based on corresponding angles, the upper left angle will be the supplement of 130, which is 50 degrees. The upper right angle is perpendicular, so it is 90 degrees. Since the sum of all internal angles of a triangle is 180, the remaining angle (lower angle) is 40 degrees. This is choice G.
Answer:
the correct answer is3 1/2
Answer:
C. 172.5 ft²
Step-by-step explanation:
area of triangular roof piece is 1/2(10)(6.9) = 34.5
there are 5 of them so 34.5 x 5 = 172.5 ft²
Answer:b
Step-by-step explanation:
B
Graph b is the only graph showing a pair of parallel lines.
Graph A are perpendicular lines and the other two are graphs that intersect. Parallel lines do not intersect each other.
