DFG
Step-by-step explanation:
It is a right triangle, and so is DEF. Thus they are similar.
3sqrt(2)
You can either use Pythagorean theorem or special triangle proportions to find the side that is parallel to z. Since in a 45-45-90 degree triangle, the hypotenuse is the leg times the square root of 2, and the hypotenuse is 3, we know that the leg is 3/sqrt(2) which is equal to 3 sqrt(2) / 2. Since z is twice this length, we know that z is equal to 2 x 3sqrt(2)/2 = 3sqrt(2)
Answer:
Step-by-step explanation:
To find the area subtract the area of the semicircle from the area of the rectangle.
Although the line isn’t there, if you imagine there is one, then you will see that you form a rectangle which is the same line as the semicircle’s diameter.
The area of rectangle is:
⇒ 
⇒ 
⇒ 
The area of the semicircle;
⇒ 
⇒ 
*Note here that the radius is half the diameter, so it is 7cm, not 14cm
⇒ 
Finally subtract the two areas;
⇒ 
⇒
