Hj and ik are opposite sides of the rectangle so they areequal in length.
19 + 2x = 3x + 22
19-22 = 3x-2x
x = -3
We can't find the length of the diagonals as we have no information about the width.
Answer:
Step-by-step explanation:
12²+16²=144+256=400=20²
so it is a right angled triangle.
let BC bebase and AB=height or perpendicular
AC=hypotenuse
sinC=12/20=3/5=0.6
cosC=16/20=4/5=0.8
tan C=12/16=3/4=0.75
similarly sin A=16/20=4/5=0.8
cos A=12/20=3/5=0.6
tan A=16/12=4/3≈1.33
Answer:
25 pieces
Step-by-step explanation:
let c = amt of candy
(c - 10 ) / 5 = 3
cross-multiply:
c-10 = 15
c = 25
add 15.15 + 8.25 which is 23.38 then 30.00 - 23.38 and you get 6.62
The answer is 40% I believe because if you add 18+12 you get 30 and 12/30 when converted is 40%
