Answer:
ab - b^2
Step-by-step explanation:
The area of the large rectangle is
A = a*b
The area of the unshaded region is
A = b*b
The area of the shaded region is the large rectangle minus the unshaded region
ab - b*b
or
ab - b^2
Well looking at this question , your answer should be option C: 3 x 3/5
35+2x=20+2.50x
subtract 2.50x
35+0.50x=20
subtract 35 frim both sides
0.50x=-15
x=-30
Answer:
x = 2.67°
GKJ = 40°
Step-by-step explanation:
Angle HKJ = 6x + 4
Angle HKG = 9x - 4
Segment bisects Angle GKJ, it means that angle HKJ is the same as angle HKG.
You have the measure of both angles in terms of x.
Angle HKJ = Angle HKG
6x + 4 = 9x - 4
4 + 4 = 9x - 6x
8 = 3x
2.67 = x
Angle HKJ:
6(2.67) + 4 = 20°
Angle HKG:
9(2.67) - 4 = 20°
Angle GKJ = HKJ + HKG = 20 + 20 = 40°
