Answer:
$255
Step-by-step explanation:
To find amount that is subtracted off of the original price, you would need to multiply 300 by 15% as a decimal
The decimal form of 15% is 0.15, meaning that you would have to multiply 300 and 0.15
Once you do this, you will get 45
To find the sale price, you need to subtract the amount that is discounted, 45, from 300
Once you do this, you will get 255
This means that the sale price of the item is $255
4.9 * 102 = 499.8
6.8 * 103 = 700.4
1.71 * 103 = 120.51
(1) See below for a diagram. Basically, the distance on the ground from the person to the building (34 ft) is adjacent to the angle of elevation (74 degrees) and the height of the building (labeled h in the diagram) is the side opposite the angle. Since we are dealing with opposite and adjacent we use the tangent of the angle and tan = opp/adj

feet.
Please be sure your calculator is set to degrees (not radians) when you do this problem.
(2) Here since P & Q are complimentary it means that their sum is 90 degrees. Since this is a right triangle that means that the remaining angle (R) must be the right angle. See below for a diagram.
sin = opp/hyp. As the sin Q = 9/41 this means that 9 is the length of the side opposite Q (the side PR) and 41 is the length of the hypotenuse. This makes the remaining side (QR) 40 in length.
cos = adj/hyp. If we focus on angle P the side adjacent (next to) is 9 and the hypotenuse is 41. Thus the cos of P = 9/41.
You could have also realized that if P & Q are complimentary the sin P = cos Q and the cos P = sin Q. We were not asked about tangent but it is also the case that tan P = cot Q and cot P = tan Q.
