The angle marked a = 120°.<br> Work out the value of x.<br><br> The diagram is not drawn accurately.
lapo4ka [179]
<h3>Answer:  x = 60</h3>

Work Shown:

a+x = 180

120+x = 180

x = 180-120

x = 60

Side note: angles 'a' and x are same side interior angles, which are supplementary whenever we have parallel lines like this.

How is this right? Can someone explain to me how to do this?
Alex73 [517]
First, we calculate the radius of the circle.
radius=diameter / 2
radius=44 ft / 2=22 ft.

Second; we calculate the area of a circle.
area of a circle=πr²
area of a circle=π(22 ft)²=484π ft²

Remember: 22²=22 * 22 =484

Answer: B) 484π ft²

0.4 miles<br> 1.69 miles<br> 3.0 miles<br> 6.4 miles
anygoal [31]

Answer:

.4 is the answer

Step-by-step explanation:

This is a right triangle problem.  We have one leg as .5 in length and the other leg as 1.2 in length.  The "straight" way to your grandma's house is the hypotenuse.  We need to find that length which will give us the distance straight from your house to their house if you didn't have to go out of your way to avoid the water.  The hypotenuse is found with Pythagorean's Theorem.  It will be filled in and solved as follows:

.5^2+1.2^2=c^2

.25+1.44=c^2

1.69=c^2

and c = 1.3

That's the straight distance.  You had to go out of your way to the tune of .5+1.2 which is 1.7 miles.  You figure out how much shorter it is taking the straight path by subtracting 1.7 - 1.3 which is .4
