The value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.

What is quadrilateral?

It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.

We have:

In the diagram below, OP is circumscribed about quadrilateral ABCD.

In a quadrilateral, the sum of the opposite angles is equal to 180 degree

x + 20 + 110 = 180

x + 130 = 180

x = 50

Thus, the value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.

I need help on the person 2 part of my assignment it’s due today please help

Answers

Answer:

Step-by-step explanation:

d is on a line with s so they are supplementary d+80 = 180 so d has to be 100

s and h are equal, therefore vertical angle x is also 80

Then 80 + 60 + y = 180 since they are on a straight line so y=40

HELP ASAP! I’m very confused and need help! Thanks!

Answers

Answer:

Step-by-step explanation:

Ok so basically 3 is 153 degrees and every line is 180 degrees, so 180-153=27.  So 3 and 2 make a line, 2 is 27 degrees and 4 and 3 make a line so that makes 4 -27 degrees. 1 is vertical to 3 and if 2 and 4 are 27 degrees and makes the lines with the other angles that equal 27 degrees then 1 is also 153 degrees.

Answers

Answer:

10a < 25b

Step-by-step explanation:

The required inequality, which represents the possible values for the number of apples and bananas purchased is 2a + 0.8b ≤20.

What is inequality?

Inequality can be defined as the relation of the expression containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
Let, the number of apples purchased, a, and the number of bananas purchased, b.


According to the question, Each apple costs $2 and each banana costs $0.80. London has a total of $20 to spend on apples and bananas.
So,
2a + 0.8b ≤20

Thus, the required inequality, that represents the possible values for the number of apples and bananas purchased is 2a + 0.8b ≤20.

Step-by-step explanation:

An event that has a probability of 1 or in other terms P(E) = 1 is said to be guaranteed to occur. This is basically stating that the event has a 100% chance of happening, meaning that no matter what the external factors turn out to be in the scenario, the event will occur regardless. 1 basically represents 100%, while lower values such as 0.5 represent 50% when dealing with these probabilities.
