Answer:
Step-by-step explanation:
∠NPK = 180° {straight line}
∠NPM + ∠MPL + ∠LPK = 180°
∠NPM + 63 +90 = 180
∠NPM + 153 = 180
∠NPM = 180 - 153
∠NPM = 27°
∠JPK = ∠NPM {Vertically opposite angles}
∠JPK = 27°
∠NPK = 180° {Straight line angle}
∠NPJ + ∠JPK = 180
∠NPJ + 27 = 180
∠NPJ = 180 - 27
∠NPJ = 153
Answer:
1/10
Step-by-step explanation:
7/10
= .7
Answer:
Step-by-step explanation:
b² - 4b - 12 = b² - 6b + 2b - 2*6
=b*(b -6) + 2*(b - 6)
= (b - 6) (b + 2)
b² - 4b - 12 = 0
(b - 6) (b + 2) = 0
b - 6 = 0 or b + 2 = 0
b = 6 or b = -2
Answer:
The answer is when we rotating something 90 degrees clockwise about the orgin
(x,y) goes to (y,-x)
