Answer:8) 76°

9) 88°

Step-by-step explanation:

Sum of exterior angles of any polygon is 360°

Exercise 8

Sum of given angles:

2x + 60° + 64° + 36° + 48° = 360°

2x + 208° = 360°

2x = 360° - 208°

2x = 152°

x = 76°

Exercise 9

Sum of given angles:

x + 90° + 109°+ 73° = 360°

x + 272° = 360°

x = 360° - 272°

x = 88°

<h3>Exercise 8</h3>

<u>Sum of given angles:</u>

  • 2x + 60° + 64° + 36° + 48° = 360°
  • 2x + 208° = 360°
  • 2x = 360° - 208°
  • 2x = 152°
  • x = 76°
<h3>Exercise 9</h3>

<u>Sum of given angles:</u>

  • x + 90° + 109°+ 73° = 360°

Select the statement that correctly compares two numbers.
sattari [20]

The correct answer is option A

• In mathematics, comparison of numbers if the process that defines similar properties between two numbers and identifies that the number if smaller or greater than or equal to the other number.

• In maths there are three special symbols used in comparison of numbers. The basic symbols are

1. Greater than (>)

2. Less than (<)

3. Equals to (=)

According to the question

Option A :

4.13 = 4.130

As we know the value of 0 after all the numbers and after the decimal is insignificant,

So , 4.13 = 4.130

This is correct comparison.

Option B :

5.16<5.06

Bigger number can’t be less than the smaller number, comparison is wrong.

Option C :

6.28<6.08

Bigger number can’t be less than the smaller number, comparison is wrong.

Option D:

7.09>7.19

Smaller number can’t be greater than the bigger number, comparison is wrong.

Option A is correct

If a function is defined by the formula y equals 2x + 1 + that domain is given by the set 3, 5, 7, 9 then which set represents t
Mariulka [41]

Answer:

{7, 11, 15, 19}

Step-by-step explanation:

The function is defined by the formula y = 2x + 1 ........ (1)

Now, domain of the function are given to be {3, 5, 7, 9}

Hence, from equation (1), at x= 3, y = 2 × 3 + 1 = 7

Now, at x = 5, y = 2 × 5 + 1 = 11

Again, at x = 7, y = 2 × 7 + 1 = 15

Finally, at x = 9, y = 2 × 9 + 1 = 19

Therefore, the range of the corresponding domain of this function is given to be {7, 11, 15, 19}. (Answer)
