Answer 1

Answer:

Answer:

4. Option A is correct.

7. Option C is correct.

8. Option A is correct.

11. Option B is correct.

12. Option C is correct

Step-by-step explanation:

The sides of equilateral triangle are same.

It is given that lengths of the sides are 9, 9, and 9.

Since the side lengths are same, therefore the given triangle is an equilateral triangle.

Option A is correct.

It is given that the line a is parallel to line b and the measure of angle 7 is 135 degree.

$\angle 6+\angle 7=180^(\circ)$ (Supplementary angles)

$\angle 6+135^(\circ)=180^(\circ)$

$\angle 6=45^(\circ)$

$\angle 4=\angle 6$ (Alternative interior angles)

$\angle 4=45^(\circ)$

Option C is correct.

$x-3=65$ (Corresponding angles)

$x=68$

$46+65+y-3=180$ (Supplementary angles)

$y=72$

Option A is correct.

11.

If a transversal line intersect two lines are parallel lines, then their corresponding angles are same.

It is given that

$\angle 1=\angle 2$

Since angle 1 and 2 are corresponding angles, therefore we can say that the lines a and b are parallel.

Option B is correct.

12.

$x-1=63$ (Corresponding angles)

$x=64$

Option C is correct.

Answer 2

Answer: The answer to #4 is A equilateral because all the sides are the same. the sides are equal.
# 7 would be c, 45 you have to make sure the sum is 180 #8 is B the same goes for that on fill in x and y. #11 isD And # 12 is c the sum must be 180.

3 - 3 × 6 + 2 = what

Answers

Use bedmass. Solve the multiplication first in this case: -3 x 6 = -18.
Now it's 3 - 18
which is -15
add -15 + 2
and that equals to -13

3-(3x6)+2
3-18+2= -13

A bicycle wheel makes five rotations. The bicycle travels 41.87 ft. Find the diameter of the wheel in inches. Use 3.14 for pi. The diameter of the wheel is about nothing in.

Answers

Answer:

The diameter is 32.04 Inches

Step-by-step explanation:

If the Bicycle makes 5 rotations and it equals 41.87 ft

Then 1 rotation around the circumference is

41.87/5 = 8.374 ft

Circumference = $\pi d$

8.374 = 3.14*d

Divide both sides by 3.14

d = 8.374/3.14

d = 2.67 ft

To convert feet to inches, we multiply by 12

d = 2.67*12 inches

d = 32.04 Inches

One number is six times another number. Their difference is 35. What are the two numbers?

Answers

Answer:

The two numbers are: 42 and 7

Step-by-step explanation:

let x be the one number and y be the other number..

As per the statement:

One number is six times another number. Their difference is 35.

⇒ $x = 6y$ .....[1]

and

$x -y = 35$ .....[2]

Substitute equation [1] into [2] we get;

$6y-y = 35$

Combine like terms;

$5y = 35$

Divide both sides by 5 we get;

y = 7

Substitute the value of y =7 in [1] we get;

$x = 6(7) = 42$

Therefore, the two numbers are: 42 and 7

7x6=42. 7+35=42. The numbers are 7 and 42.
