Answer:
a = 49°
Step-by-step explanation:
OB = OC ( both radii of the circle ), thus
Δ BOC is isosceles and the base angles are congruent, that is
∠ OBC = ∠ OCB = 41° , so
∠ BOC = 180° - (2 × 41)° = 180° - 82° = 98°
The angle on the circumference BAC is half the angle at the centre for angles subtended on the same arc , thus
a = 0.5 × 98° = 49°
Answer:
12.5 pounds
Step-by-step explanation:
If he has 100 lbs of dog food, and you need to evenly distribut it, do
100/8 =12.5
Slope =2/3
70,80) (10,40)
(80-40)/(70-10) = 40/60
4/6
2/3

Answer:
Step-by-step explanation:
This can be modelled with the variable x to represent the "groups"
3x + 2
Multiplifcation means groups of.
3x is 3 times x, which is 3 groups of x.
