Step-by-step explanation:
10. [-19-(-20) - (-34)] ÷ (-6)
= (-19+20+34) ÷ (-6)
= 35 ÷ (-6)
= -5.83
12. [-18 - (-66) -22] × 2
= [-18+66-22] × 2
= 26 × 2
= 52
Answer:
9.2
Step-by-step explanation:
So the 14 can be divided equally on both sides by the fact that the line cutting it at right angle bisects it.
Thus having 6 and 7 as the two shorter sides of a right angled triangle will help us get the radius( hypotenuse in this case) using the square root of the sum of the squares of both six and 7, the Pythagoras theory.
this leads to 9.2 as our answer
The first thing you need to do is find the radius of the semicircle. To do that you look to see that the width of the rectangle is the same as the radius. Once you have the Area of a Semicircle calculated multiply it by 3. then, we know that the other length of the rectangle is 3 diameters of a semicircle this means that you multiply the radius of 7 by 6 which gives you 42. You take the area of the rectangle (294) and subtract the area of the 3 semicircles(230.79) Which gives you the answer of 63.21cm^2
Answer:
the value of x= 5
Step-by-step explanation:
hey there!
given;
<em>∠</em><em>P=90°( right angle)</em>
<em>now;</em>
<em>∠p=19x-5</em>
<em>90°+5°=19x</em>
<em>95/19=x</em>
<em>x=5</em>
<u><em>hope it helps!</em></u>

The measure of the interior angle of a regular 30-gon is 168 degree
and its exterior angle is 180-168=12 degree
