Find the tangent of angle I. Dont round.​

SAT
1 answer:
Dmitriy789 [7]3 years ago
5 0

Answer:

tangent of angle I = \sqrt{22}/\sqrt{59}) or \sqrt{22/59}

Explanation:

tangent = opposite/adjacent

we need to solve for the opposite side, using pythagorean theorem

(\sqrt{59})^2 + b^2 = 9^2

59 + b^2 = 81

b^2 = 22

b = \sqrt{22}

tangent = opposite/adjacent

tangent of angle I = \sqrt{22}/\sqrt{59}) or \sqrt{22/59}

Amiraneli [1.4K]
At first situation, ratio = x/y = 1/5
5x = y  -------Equation (i)
Now, after adding 5 more red, it is = x + 5 / y+5 = 1/3
y+5 = 3(x + 5)
y + 5 = 3x + 15
y - 3x = 15 - 5

Substitute the value of y from equation (1), 
5x - 3x = 15 - 5
2x = 10
x = 10/2
x = 5

Originally, There were 5 red marbles in the bag

Hope this helps!

It’s takes 5100 Nof force to accelerate a Ford Mustang 3 m/s2 what is the mass of the car
xxMikexx [17]

The force is 5100 N which is accelerating a Ford Mustang. The mass of the car is 1700 kg.

<h3>What is force?</h3>

A force is an influence that can alter an object's motion. A force can modify the velocity of a mass item. Force is calculated in Newton.

In physics, mass is a quantitative measure of inertia, which is a fundamental property of all matter. Mass is measured in kilograms and grams.

The force is given as 5100 N

The acceleration is 3 m/s

The mass is to be calculated

F =  ma

m = F / a

m = 5100 / 3

m = 1700 kg

Therefore, the mass of the car is 1700 kg.

To learn more about force, refer to the link:
