Answer: side c is 20!
Step-by-step explanation:
So since this a right-angled triangle, you might want to use the Pythagorean Theorem. First, use the formula A(squared) + B(squared) + C(squared). Since c is unknown just put that as x(squared). Then, answer A(squared) and B(squared which would be 16mm and 12mm in this case. Multiply 16*16.... and you get 256. Then do the same to side B which is 12 and you get 144. Then know you can add them both together and get 400. What is the square root of 400? Yes, it’s 20. And there is you answer!
Sum of the angles of any quad =360
then y+(x+2)+(x-2)+(x-10) = y +3x -10 =360 (by adding both sides by 10)
y + 3x =370 ;.... eq 1
the sum of each two opposite sides in a quad inscribed in a circle =180
then (x+2)+(x-2)=180
therefore 2x =180
therefore x=90 (sub in eq 1)
y+3*90 =y +270 = 370 (subtracting both sides by 270)
therefore y=100
then measure angle B=100 degrees
A=92 degrees
C=88 degrees
D=80 degrees
