Answer:
l=10 cm
Step-by-step explanation:
In a rhombus, the diagonals are cut into identical lines at the intersection.
This way, I found the measures of the halves of the diagonals in a right triangle, knowing that the diagonals of the rhombus are perpendicular on each other.
I calculated that AO = AC/2= 8, and that BO=BD/2= 6, and then I applied pytagora's theorem in a quarter of the rhombus, which is the right triangle AOB, to find the length of a side
Answer:
centre=(25,-17)
radius=19
Step-by-step explanation:
comparing with the formula
(x-h)^2+( y-k)^2=r^2

Q 15/50 3/10
R 8/50 4/25
S 3/50 3/50
T 24/ 50 12/25
Imagine right triangle with first leg to be the Chad length and second leg to be the Chad's shadow. Second leg has length 14.3 ft and since t<span>he straight-line distance from the top of Chad’s head to the end of the shadow creates a 23° angle with the ground, you could consider the trigonmetric function

14) 51. You divide 100 by 60 and multiply the answer by 85%.
15) about 200 students loved music. You would round the 398 to 400 and the 52% to 50%, which is half.
16) They would cost the same because adding all of the discount together for the first computer would equal 30% which is the same amount as the second computer.
Hope this helped you!
