Just use the inverses: sin^-1, cos^-1, and tan^-1. For example, #13, you would type in your calculator, tan^-1 (30/33), and then you'll get 43.15 degrees.
Answer:
The posters cost $52.07.
Step-by-step explanation:
First, you have to calculate the cost of the 20 posters by multiplying the price per poster for the quantity:
$2.89*20=$57.8
Then, you have to calculate the 15% discount by multiplying the cost for 15% and subtracting that amount from the cost:
$57.8*15%=$8.67
$57.8-$8.67=$49.13
Finally, you have to calculate the 6% of $49.13 and add the result to that amount:
$49.13*6%=$2.94
$49.13+$2.94=$52.07
According to this, the answer is that the posters cost $52.07.
<u>Given</u>:
Two parallel lines are cut by a transversal and form a pair of alternate interior angles.
One angle measures (6x + 5)° and the other measure (7x - 4)°
We need to determine the measure of each angle.
<u>Value of x:</u>
Since, the two angles are alternate interior angles, then the two angles are congruent.
Thus, we have;




Thus, the value of x is 9.
<u>Measure of each angle:</u>
The measure of each angle can be determined by substituting
in the measures of each angle.
Thus, we have;


Thus, the measure of each angle is 59°
Oh.......kay.... Is that a question? It doesn't look like one.
