First, tan(θ) = sin(θ) / cos(θ), so if cos(θ) = 3/5 > 0 and tan(θ) < 0, then it follows that sin(θ) < 0.
Recall the Pythagorean identity:
sin²(θ) + cos²(θ) = 1
Then
sin(θ) = -√(1 - cos²(θ)) = -4/5
and so
tan(θ) = (-4/5) / (3/5) = -4/3
The remaining trig ratios are just reciprocals of the ones found already:
sec(θ) = 1/cos(θ) = 5/3
csc(θ) = 1/sin(θ) = -5/4
cot(θ) = 1/tan(θ) = -3/4

What is the HCF of 130,325 and 845
Answer:
The HCF of 130, 325 and 845 is equal to 65.
Step-by-step explanation:
We need to find the HCF of 130, 325 and 845.
First, we see the prime factors of the above numbers i.e.
The factors of 130 are: 1, 2, 5, 10, 13, 26, 65, 130
The factors of 325 are: 1, 5, 13, 25, 65, 325
The factors of 845 are: 1, 5, 13, 65, 169, 845
Then the greatest common factor is 65. So, the HCF of 130, 325 and 845 is equal to 65.

Depending on traffic, Danielle’s drive to the park is p minutes from work and 90 minutes from the park to her home. If Danielle’s total commute (c) took two hours today, how long was Danielle’s drive to the park from work? Set up your equation when total commute time (c) depends on the time to drive to the park (p).
Equation: ______________
p=88 minutes
p=70 minutes
p=40 minutes
p=30 minutes
Answer:
The equation is;
p + 90 = 120 minutes
Danielle’s drive from work to the park took 30 minutes ( p = 30 minutes)
Step-by-step explanation:
Here, we want to write and solve an equation
Here, we want to get the time taken by Daniele from the park to work
From the question, the total commute is two hours
since 1 hour is 60 minutes, it follows that 2 hours is 120 minutes
Now, if we added the time taken to commute both journeys, we have the total as 2 hours
This means;
p + 90 = 120 minutes
p = 120 - 90
p = 30 minutes

A shopkeeper buys a stove from a manufacturer for $100.The selling price if he makes a profit of 15%
Answer:Selling Price = $115
Step-by-step explanation:
Selling price = Cost price + Profit
Cost price = $100
Profit = 15% = 15% x 100 = $15
Selling Price = $100 + $15= $115
OR
Selling Price = Cost price + Profit
Selling Price =$100 + (15% of $100)
Selling Price = $100+ $15
= $115.
