X = 45.

Since opposite exterior angles are congruent, you can set the 2 values equal to each other. When you solve for x, you should get 45.

Answer:

As there is one math problem over there.

Lets see the question first:

It says that "A hair dryer is rated $1200\ W$ ,if you use the dryer for $0.25\ h$ .How much electric energy do you use ?"

Final answer = Electic energy $=0.3\ kW\ h$

Step-by-step explanation:

Electrical Energy $E=Power \times time$ .

The total amount of electrical energy used depends on the total power used by the electrical device and the total time they are used for.

So we have been given the power of the hair dryer $=1200\ W =\frac{1200}{1000}=1.2\ kW$

Now the time it has been use for $=0.25\ hrs$

To calculate electric energy we will multiply both the terms.

Electric energy $=0.12 \times 0.25 =0.3\ kW\ h$

So electric energy used for the hairdryer is = $0.3\ kW\ h$

I think the best answer would be F.
When √10 is converted into a decimal it is 3.16, and F is the most close to that.
Hope this helps!
