Answer:
15
Step-by-step explanation:
We can find value of x using similarity ratio
(3x-5)/32 = (5x-5)/56 cross multiply expressions
56×(3x-5) = 32×(5x-5)
21x - 20x = 35 - 20
x = 15
Answer:
36
Step-by-step explanation:
Answer: ∠DOB: 48°
Step-by-step explanation:
1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°
2. now we can solve for the missing variable, n.
108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°
3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°
hope this heped! ♡
Card K is reflected over the y-axis; while card N is reflected over the x-axis
6/4= 1.5
8/4= 2
As you can see, this is a proportional relationship.
The scale factor is 4.
I hope this helps!
