To Find : Area of triangle = ?[tex] \\ [/tex]
Solution :As, we have :
Base of triangle, b = 8 cmHeight of triangle, h = 4 cm[tex] \\ [/tex]
So, to find area of triangle we have a formula :
[tex] \large \underline{\boxed{\bf{Area_{(triangle)} = \dfrac{1}{2} \times b \times h}}}[/tex]
[tex] \tt : \implies Area = \dfrac{1}{2} \times 8 \: cm \times 4 \: cm[/tex]
[tex] \tt : \implies Area = \dfrac{1}{2} \times 32 \: cm^2[/tex]
[tex] \tt : \implies Area = \cancel{\dfrac{32}{2}} \: cm^2[/tex]
[tex] \tt : \implies Area = 16 \: cm^2[/tex]
[tex] \\ [/tex]
Hence, area of given triangle is 16 cm².

I'm trying to do a Desmos activity, help!
9514 1404 393
Answer:
4 feet
Step-by-step explanation:
Desmos is useful for finding the answer to this. The problem statement tells you the angle with the x-axis is 75°. If we put the ladder in the first quadrant, the slope will be -tan(75°). We can raise its end to the 15 ft level by making the y-intercept be 15. Then the x-intercept answers the question: 4 ft.

Additional comment
The angle mode needs to be set to Degrees in the Desmos settings for this equation to produce the correct graph.

A family buys 5 airline tickets online. The family buys travel insurance that costs $17 per ticket. The total cost is $890. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket.
Answer: Equation that represents this situation is 5(x+17) = 1495,
Price of one ticket is 282
Step-by-step explanation:
Here x represents the price of one ticket,
Also, a person bought travel insurance that costs $17 per ticket.
Hence, the total cost of a person = x + 17
⇒ The total cost of 5 person = 5 ( x + 17 )
But, According to the question,
5 ( x + 17 ) = 1495
⇒ x + 17 = 299
⇒ x = 299 - 17
⇒ x = 282
Hence, the price of one ticket = $ 282

Mr. and Mrs. kinkaid open a certificate of deposit account that pays 1.45% interest compounded daily. How much interest will the account earn in 5 years on their deposit of $8,500? SHOW ALL WORK FOR CREDIT.
Answer:
After 5 years, the account will have earned $ 639.13 in interest.
Step-by-step explanation:
Given that Mr. and Mrs. kinkaid open a certificate of deposit account that pays 1.45% interest compounded daily, to determine how much interest will the account earn in 5 years on their deposit of $ 8,500, the following calculation must be performed:
X = 8500 (1 + 0.0145 / 365) ^ 5x365
X = 8500 (1 + 0.0145 / 365) ^ 1825
X = 9,139.13
9,139.13 - 8,500 = 639.13
Thus, after 5 years, the account will have earned $ 639.13 in interest.
Find the missing angle.
SHOW YOUR WORK!
Answer:
120º
Step-by-step explanation:
All of the interior angles of a triangle have to add up to 180º, so the missing interior angle is 60 degrees once you add 24 and 96 and subtract the sum of 120 from 180.
As for the missing angle, it's supplementary with the interior one that was originally unknown. Subtract 60 from 180, and that will give you 120º.

Step-by-step explanation:
how can using trigonometry you can find the height of a flagpole?
Answer:
As for the trig functions (sine, cosine, and tangent), you can use the angle you are interested in, θ, and the lengths of the sides of the triangle based off of angle θ to find an unknown length in the triangle.
sinθ = [tex]\frac{opposite}{hypotenuse}[/tex]
cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex]
tanθ = [tex]\frac{opposite}{adjacent}[/tex]
Essentially, if you know the measure of one of the angles in the triangle (not including 90°, and the measure of at least one side length, you can select the proper trig function that will allow you to find the unknown length, or height, of the flagpole.
Ex:
Let's say you are standing 18 feet away from the base of the flagpole, and you know (somehow) that an imaginary line is formed from the top of the flagpole to your feet (this imaginary, slanted line is our hypotenuse) and that the angle between that imaginary line and ground is 30°.
We will use 30° as our θ. In this situation, the unknown side length (the height of the flagpole) is opposite from this angle we have chosen. So it is our "opposite". We know that the distance between you and the base of the flagpole is 18 feet. Because this is not that slanted, imaginary line we formed before, this is not the hypotenuse. This is a side length that is adjacent to where we are standing, where our angle θ is. So 18 feet is our "adjacent".
The trig function that includes both "opposite" and "adjacent" is the tangent function, or tanθ = [tex]\frac{opposite}{adjacent}[/tex].
We have selected our trig function:
tanθ = [tex]\frac{opposite}{adjacent}[/tex]
Substitute in the known values. θ = 30° adjacent = 18
tan(30°) = [tex]\frac{opposite}{18}[/tex]
Multiply both sides of the equation by 18, to remove 18 from the right side of the equation:
(18)·tan(30°) = [tex]\frac{opposite}{18}[/tex]·18
The 18's cancel because that side becomes [tex]\frac{opposite 18}{18}[/tex] and a number divided by itself is equal to 1. And multiplying the opposite by 1 still equals the opposite.
So we are left with:
(18) · tan(30°) = opposite
At this point, simply input tan(30°) into your calculator (make sure your calculator is in degrees, not radians, by checking MODE), then multiply the result by 18.
This should equal about 10.3 = opposite. This means that 10.3 feet is the height of the flagpole.
