Scalene triangle, this is because there are three sides and all of them are different.
Ok, so x and 67 are supplementary, so you can set up the equation x+67=180.
x=180-67
x=113
Since this is a picture of two lines with a transversal, you know that the angles around the lines are the same. Since x and y are alternate interior angles, they are equal.
So, both x and y equal 113.
23=.25(100)-3
23=25-3
23≠22
The equation is not correct therefore, it is false
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;
⇒
⇒
