Plug the values for a, b, and c in the expression given.
Answer:
a) 39 degrees
Step-by-step explanation:
angle REB + angle JEB = 180 degrees (because J, E, and R are collinear)
=> angle REB = 180 - angle JEB = 180 - 132 = 48 degrees
angle REB + angle ERB + angle RBE = 180 degrees (because the sum of 3 angles inside a triangle is 180 degrees)
=> angle RBE = 180 - angle REB - angle ERB = 180 - 48 - 93 = 39 degrees
Answer:
Q1) D
Q2) C
Step-by-step explanation:
Q1)
y ∝ x
y = kx
Let x=-1,y=2
2 = k(-1)
k = -2
Q2)
directly (y=kx)
Let x=2,y=4
4 = k(2)
k = 2
y = 2x
inverse (y = k/x)
Let x=2,y = 4
4 = k/2
k = 8
xy = 8
