Answer:
40° and 140° (with x = -10)
Step-by-step explanation:
Since the angles are supplementary (when added, equal 180°), you can add the two angles together to get (-18x)°. 180/-18 = -10 for x. Fill in -10 for x in both expressions. (-14 • -10)= 140° and (-4 • -10)- 40°. 140+40=180
Answer:
24 m^2
Step-by-step explanation:
There are two areas to consider here: first, the area of the wall, and second, the area of the window. We answer this question by finding these two areas and subtracting the area of the window from the area of the wall.
Wall area: (4 m)(7 m) = 28 m^2
Window area: (2 m)(2 m) = 4 m^2
Net area of wall, to be covered in brick:
28 m^2 - 4 m^2 = 24 m^2
