It is D
Because the amount of the inside angles of an triangle are equal to 180 degrees
And a straight line is 180 degrees
The factored form of this expression would be :
(k-3h)(k+3h).
The sum of all the angle measures is 180 degrees, now lets set up some equations:

Thus x = 22
Hope that helps!
Answer:
x = 116° , y = 20°
Step-by-step explanation:
Since, measure of angle subtended on the center of the circle is twice the measure of angle subtended on the circumference of the circle.
Now, by angle sum property of a quadrilateral.

Answer: formula - (x/4)+x
Step-by-step explanation:
Since there are no numbers, here is just the formula and what it means :)
(x/4)+x
(btw x is whatever your number is)
so what you need to do first is to divide your number by 4 because 25% is 1/4 of 100%
and then add that number that you just got to your number.
Its a little confusing to say out in words, so here is an example using 24
24/4=6
24+6=30
and heres another example using 50
50/4=12.5
50+12.5=62.5
I hope this helped! <3
