The two angles given are two angles of a triangle, so the third angle must be:
SPR=180-RSP-PRS
SPR=66°
First part: 1 is less than the sum of x and 3: 1 < x+3.
Second part: the sum of x and 3 is less than 9.
Obviously 1 < 9.
Taking another look at 1<x+3, we can solve for x: -2<x. Draw a dashed vertical line thru x = -2.
Taking another look at x+3<9, subtract 3 from both sides. Then x<6.
Draw a dashed vertical line thru x=6.
Shade the area between these two vertical lines to obtain the desired graph.
You knew where to place the target based on the coordinates (-5,4). Starting from the origin (0,0), we know how many units to move to horizontally and vertically. We move the target 5 units to the left, because it is negative. We move the target 4 units up, because it is positive. (x,y)
900 is the answer of 2 squared times 15 squared
5^3 Sartre 10 + 4^3 sqrt 10
