Given the figure below, calculate the area
Aleksandr [31]

Answer:

<em>1+√3</em>

Step-by-step explanation:

Area of the triangle = 1/2 * base * height

Area of the triangle = 1/2 * AC * BD

We need to get AC

AC = AD+DC

Get base AD using SOH CAH TOA

tan 45 = 4/AD

AD = 4/tan45

AD = 4/1

AD = 4

Get DC

tan 30 = 4/DC

DC = 4/tan 30

DC = 4/(1/√3)

DC = 4√3

AC = 4 + 4√3

AC = 4(1+√3)

Get the Area of the triangle

<em>Area = 1/2 * 4 *  4(1+√3)</em>

<em>Area of the triangle = 1+√3</em>

Jake tossed a paper cup 50 times and recorded how it landed. the table shows the results:
Darya [45]

The experimental probability of each event is as follows:

  • Landing open side up = 1/50 = 0.02 = 2%.
  • Landing closed side up = 5/50 = 1/10 = 0.1 = 10%.
  • Landing on its side = 44/50 = 0.88 = 88%.

The experimental probability of an event is the ratio of the number of outcomes that favored the event to the total number of outcomes in the experiment.

In the question, we are given that Jake tossed a paper cup 50 times and recorded the position how it landed, which is shown in the table:

Open-sided up: 1

Closed side up 5

On the side: 44.

We are asked to determine the experimental probability of each outcome.

The number of outcomes, when the landing is open-sided up is 1.

The number of outcomes, when the landing is closed-sided up is 5.

The number of outcomes, when the landing is on the side up is 44.

The total number of times the experiment took place is 50.

Thus, the experimental probability of each event is as follows:

  • Landing open side up = 1/50 = 0.02 = 2%.
  • Landing closed side up = 5/50 = 1/10 = 0.1 = 10%.
  • Landing on its side = 44/50 = 0.88 = 88%.

Veseljchak [2.6K]

Answer: 1100

Step-by-step explanation: mark x for the total sum.

0.35x+ 0.20x + 495 = x. 495= x-0.35x-0.20x

495= 0.45x. X= 495/0.45
