Work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
The equation
a/4 = 2/3
do cross multiplication
8 = 3a
a = 8/3
Performing the expression.
= (a - 4) / 4
= (8/3 - 4) / 4
= (8-12 / 3)/4
= -4/3 / 4
= -1 / 3
So the answer is letter b.
Answer:
For this question, we can assume that the lines are parallel.
Step-by-step explanation:
This means that angle 1 is congruent to angle 11.
Afterwards, we know that angle 11 + angle 12 equal a straight line, or 180º.
If angle 11 is congruent to angle 1, that means measure angle 11 = 112º.
Then, we subtract 112 from 180 which would give us 68.
Therefore, the answer is 68º.
A is correct. Cosecant is defined as the reciprocal of sine.
B is also correct...
