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! ♡
Answer:
28
Step-by-step explanation:
area = width x height
area = 7 x 4
area = 28 square feet
The angle measures tell you the triangles are similar, so corresponding sides will have the same ratio.
GX/BX = UH/NH
GX = BX·UH/NH
GX = 7·18/(3√11)
GX = (42/11)√11
GB/BX = UN/NH
GB = BX·UN/NH
GB = 7·15/(3√11)
GB = (35/11)√11
Answer:
You divide 5 by 47 and then see if the fourth digit after the decimal is 5 or greater or less than 5. If it's less, the digit before it remains the same and the decimal cuts off at it. If it's 5 or greater, the digit before it goes up one and the. decimal cuts off at it. Using this, you should get 0.106, I think.
Hey there!
To find the discount, just multiply the original price by the percent.
49*.65= 31.85(how much it was taken off)
Now subtract31.85 from 49 and you'll get
17.15
$17.15 is now the new price
