Question

Help please 4, 5, 6.......

Answer 1

4. Supplementary angles together make a straight line (two right angles). So BOE is supplementary to BOC

Answer: ∠BOE

5. Distance and midpoint between (4,-2), (6,8)

`d = √( (6-4)^2 + (8 - -2)^2) = √(2^2+10^2)=√(104)=2 √(26)`

midpoint

`\left((4 + 6)/(2), (-2 + 8)/(2) \right) = (5, 3)`

Answer: distance 2√26, midpoint (5, 3)

6.That's a rectangle oriented parallel to the axes, width parallel to the x axis of 7 - -3 = 10 and length along y of 1 - - 4 = 5, so an area of 10(5)=50

Answer: 50
