Answer:
sin a = 7/25
cos a = 24/25
tan a = 7/24
Step-by-step explanation:
Trig. How wonderful. I get tripped up on these types of problems some times, so I decided to try to help! To start, write out the three ratios.
SOH (sine=opposite/hypotenuse) CAH (cosine=adjacent/hypotenuse) TOA (tangent=opposite/adjacent)
Then, label the triangle with “hypotenuse” “adjacent” and “opposite.” This helps us correctly use and find the raitos. Then, use these ratios to find out the ratios of A!
sin a = 7/25
cos a = 24/25
tan a = 7/24
If needed, just divide the ratios to get their decimal form!
Answer:
The total price of the groceries, including discount and tip is $110.4.
Step-by-step explanation:
Here, the bill amount of groceries = $120
Now, the coupon off = 20%
Calculating the discount, we get
20% of bill amount $120 = 20% of 120 =
So, the 20% discount on the bill amount = $24
The actual payable amount = Bill Amount - Discount
= $120 - $24 = $96
Now, 15% tip is also applied on the actual payable amount $96.
15% of 96 =
So, the total price t = Payable amount + Tip amount
= $96 + $14.4 = $110.4
or, t = $110.4
Hence, the total price of the groceries, including the discount and the tip is t = $110.4.
