Answer:

Step-by-step explanation:

What it means to "solve for a triangle" is to basically find ALL the missing parts, which in this case, are the lengths.

You are given the angles of the triangle, which we can use to help find the lengths.

By using sin, cos, and tan we can find the missing lengths

** quick side note, an easy way to remember how to use sin, cos, tan is SOH CAH TOA. In other words "for sine, multiply the opposite and hypotenuse, for cosine, multiply adjacent and hyp., and for tan, multiply opposite and adj.

start w/ solving for an angle (it doesn't matter which one but ill do A)

Bc you aren't given any side lengths, you have it a little easier by having to only use one method of SOH CAH TOA to solve. The method is sine

Using your calculator, type in sin(degree) or sin(51), and  you should get

= 0.777145 OR 0.8

** make sure your calculator is is DEGREES not RADIANS

Now do this for the rest of the angles:

sin(7)= 0.1

sin(10)= 0.2

You have all the lengths (0.8, 0.1, 0.2) add them together to find the perimeter and if you want to find the area use Bh/2. But to find the area you must have a height, which you don't have

To find the height use formula: sqrt/( S(S-A)(S-B)(S-C)

A, B, C are the sides you've found using sine, and S is 1/2( A+B+C) or fast math is 0.55.

Plug in the values and solve :)

iragen [17]

Answer:

We have

Stock = $200

Bonds = $100

Substitute these values into 1.08s+1.02b, where 's' is stock and 'b' is bond

.() + .() =

Predicted end of year value is $318

babunello [35]

Non-linear graph best describes this function.

<h3>Why nonlinear?</h3>

As described in the question, Pauley graphs the change in temperature of a glass of hot tea over time. He sees that the function appears to decrease quickly at first, then decrease more slowly as time passes. It is linear because the graph decreases over time. It is linear because there is both an independent and a dependent variable but it doesn't satisfies one condition of being linear. Thus, It's Nonlinear because linear functions are increasing functions. It is nonlinear because linear functions increase or decrease at the same rate.

What is the height of an equilateral triangle if the sides are 10
4vir4ik [10]

Answer:

The height of the equilateral triangle is 5\sqrt{3}\ units

Step-by-step explanation:

we know that

An equilateral triangle has three congruent sides, and three congruent angles that each measure 60 degrees

To find out the height of an equilateral triangle, apply the Pythagoras Theorem in the right triangle ABD

Remember that the height of an equilateral triangle bisects the base.

see the attached figure to better understand the problem

AB^2=AD^2+BD^2

substitute the given values

10^2=5^2+BD^2

Solve for BD

100=25+BD^2

BD^2=100-25

BD^2=75

BD=\sqrt{75}\ units

simplify

BD=5\sqrt{3}\ units`

therefore

The height of the equilateral triangle is 5\sqrt{3}\ units
