When you have two parallel lines being cut by a transversal, you can use the next statements for the angles:
The measurement of the angles in green is the same (are congruents)
The measurement of the angles in blue is the same (are congruents)
An angle in green is a complementary angle with an angle in blue. (The addition of the two angles has to be 180º)
You know that:
As the angle 3 is congruent with angle 2:
Given:
The demand function is,
The total revenue function is,
Answer:
A^2 = b^2 + c^2 - 2bc cos a
= 11^2 + 5^2 - 2*5*11 cos 40
= 7.86 to 2 DP's
to find the remaining angles use the sine rule:-
a / sin A = b / sin B so
7.857/ sin 40 = 11 / sin B
sin B = 11 sin40 / 7.857 = 0.8999
<B = 64 degrees
so <C = 180 - 64-40 = 76 degrees
Answer:
Step-by-step explanation:
150 students/3 classes= 50 students per class
Answer:
It’s equivalent.
Step-by-step explanation:
Collect like terms: 4x+12 = 4(3+x)
Expand brackets: 4x+12 = 12+4x
Rearrange: 4x+12 = 4x+12
