### Answers

**Answer:**

x = 40°

**Step-by-step explanation:**

angle A is a vertical angle with 60 so it's 60

60+80 = 140

180-140 = 40

**Answer:**

[tex]\boxed{\tt x=40^{\circ}}[/tex]

**Step-by-step explanation:**

∠x, ∠BAC, and ∠CAF form a straight line.

***Sum of angles that are formed on a straight line is equal to 180°.***

[tex]\tt \angle x+\angle BAC+\angle CAF=180^{\circ}[/tex]

[tex]\tt x+\angle BAC+\angle CAF=180^{\circ}[/tex]

[tex]\tt x+80^{\circ}+\angle 60^{\circ}=180^{\circ}[/tex]

Add,80°+60°=140°

[tex]\tt x+140^{\circ}=180^{\circ}[/tex]

Subtract 140 from both sides:

[tex]\tt x+140^{\circ}-140^{\circ}=180^{\circ}-140^{\circ}[/tex]

[tex]\tt x=40^{\circ}[/tex]

A 1kg book is lifted 2m. How much work was done?

### Answers

**Answer:**

work= force ×distance

force= mass × acceleration due to gravity

mass= 1kg

acceleration=10

Force=1×10=10N

Work=10×2=20joules

The **work done **is 20 **joule**.

What is Work done?

It should be **converted **to **energy **in order to **move **an **object**. Energy can be transferred by the use of force. Work done refers to the **amount **of **energy **used by a **force **to **move **an **object**.

Given:

**mass**, m= 1 Kg

So, **force **= mg = 1 x 10 = 10 N

and, **displacement **= 2m

Now, **work done**= force x displacement

= 10 x 2

= 20 Joules.

Hence, the **work done **is 20 joule.

PASS IS INTERCEPTED AT THE GOAL LINE BY MALCOLM BUTLER

Roberto earns $6.50 per hour. He worked 32 hours at the regular rate, 8 hours at a time and a half, and 8 at double time. How much did he earn?

### Answers

**Answer $390**

**Step-by-step explanation:**

**Answer:**

$390

**Step-by-step explanation:**

First Roberto works 32 hours at 6.50 per hour. At that time, he earn 32*6.5 = **$208**. Then he works 8 hours at a time and a half. This means that his pay rate is 50% more, or 6.5*1.5 = $9.75 per hour. Since he worked 8 hours at this pay rate, he earns 8*9.75 = **$78**. And then he works 8 hours double time. This means his pay rate was doubled during that duration. 6.5*2 = 13, 13*8 = **$104**.

Total: 208 + 78 + 104 = $390

Find the missing angle measurement in the triangle.

### Answers

**Answer:**

the answer is C

**Step-by-step explanation:**

the right angle is = 90

the other angle= 55

so you add them together which makes 145

so subtract 180 which is = to a triangle subtract 180-145=35

**Answer: C.) **

**Step-by-step explanation:**

Triangle angles add up to 180 degrees.

The box is a right angle which equals 90 degrees.

55 degrees + 90 degrees = 145 degrees, but we need the sum to be 180, so we subtract 145 from 180 and you should get the answer of "35".

Find the unknown angle

### Answers

**Answer:**

A = 45°

**Step-by-step explanation:**

All angles in a triangle add up to 180°.

We know that one angle in the triangle is 90° (this is known because of the small square).

Hence:

A + A + 90° = 180°

Simplify

2A + 90° = 180°

Rearrange

2A = 180 - 90

2A = 90

Divide both sides by 2, so that A is by itself

A = 45°

If m+6 divided by 2 is 4 less than 4m. What is the value of m?

### Answers

**Answer:**

Ok

**Step-by-step explanation:**

m = 2

(m+6)/2 = 4m-4

multiply each side by 2

m+6 = 8m-8

subtract m from both sides

6 = 7m-8

add 8 on both sides

14 = 7m

divide both sides by 7
