Answer:

no 1 and no 3= 133

no 2 = 47

Step-by-step explanation:

according to rules of geometry opposite angles are equal

-> no.4=no.2 and no.1 = no.3

->the another angle will 180-47=133 because there is no bended line

Answer:

[tex]\boxed{\textsf{The value of x is \textbf{7}.}}[/tex]

Step-by-step explanation:

Given that 9213x5 is a multiple of 9 and we need to find out the value of x .So the rule for divisibility for 9 is :-

Test for Divisibility by 9 :-

A number is divisible by 9 if the sum of the digits is divisible by 9 .

Here the sum of the digits is :-

[tex]\sf\implies Sum_{(digits)}= 9+2+1+3+x+5=\pink{20+x}[/tex]

Now here to make 20 +x divisible by 9 is should be equal to 27 since 27 is the nearest smallest multiple of 9 .

[tex]\sf\implies 20 + x = 27 \\\\\sf\implies x = 27-20 \\\\\sf\implies\boxed{\pink{\sf x = 7 }}[/tex]

Answer: B.   4x + 17 = 23

Answer:

Step-by-step explanation:

A rotation is a transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point. The fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.

Therefore, the fixed point is called the center of rotation.

What are the angles?

Angles are formed when two lines intersect at a point. The measure of the 'opening' between these two rays is called an 'angle'.

A rotation means that the transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point.

So,the fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.

Hence, the fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.

Mac must get 90 on the eighth exam to raise his average to 80%.

The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the total number of observations by the total number of observations.

Given:

Mac has taken seven math exams this year.

His average mark is 78%.

Let x be the required score.

To find the mark to raise his average to 80%:

According to the question,

78(7) + x  = 8(80)

546 + x = 640

x = 640 - 546

x = 90

Therefore, the required mark is 90.
