Answer:
150ft²
Step-by-step explanation:
surface area = (2×½×8×3)+(8+5+5)×7
= 24+126
= 159 ft²
Answer:
3 angles?
Step-by-step explanation:
7:
Parallel lines have the same slope
y = -3x + b
Plug in the x and y values from the point
5 = -3(-4) + b
5 = 12 + b
-7 = b
Answer to 7: y = -3x -7
8:
Perpendicular lines have opposite reciprocal slopes
y = -2x + b
Plug in x and y from the point
-6 = -2(7) + b
-6 = -14 + b
8 = b
Answer to 8: y = -2x + 8
