The value of x in all case is

1. The value of x is 2

2. The value of x is 1

3.The value of x is 57

4.The value of x is 93

<h3>What is complementary and supplementary angle?</h3>

If the sum of two angles is 180 degrees then they are said to be b angles, which form a linear angle together. Whereas if the sum of two angles is 90 degrees, then they are said to be complementary angles, and they form a right angle together.

1. As the given angle is 90 degree i.e., complementary angle.

So,

54+10x+16=90

20=10x

x=2

2. 65x-12=43x+10  (Vertically opposite angle)

 22x= 22

x=1

3. 72= x+15  (Vertically opposite angle)

x= 57

4.x+244+23=360  (Complete angle)

 x=93

Probability is used when describing a function of a parameter given an outcome. For example, if a coin is flipped 10 times and i
Paladinen [302]

Answer: 1/1024

Step-by-step explanation:

When a fair coin is flipped the coin would show either head or tail meaning only 2 outcomes are possible. So, getting an head means 50% chance or 1/2 chance.

Now, it means chance for 10 times head every time= (1/2)^10

Chance= 1/1024

Chance= 0.00097

A triangle has side lengths measuring 20 cm, 5 cm, and n cm. Which describes the possible values of n? 5 &lt; n &lt; 15 5 &lt; n
ehidna [41]

Answer:

15 < n < 25

Step-by-step explanation:

According to the triangle inequality theorem, any two sides lengths' sum should be greater than the third side. This also implies that to find the <em>possible length of  the 3rd side given other two sides (let two given sides be x and y)</em>, we can say that the 3rd side length will be between x+y and x-y.

Hence, we can say that <em><u>n should be between 20+5 and 20-5</u></em>.

So, 20 - 5 < n < 20 + 5, which is

15 < n < 25

<em>This is the correct answer.</em>
