Answer:
NC = 7.7
C = 63.6°
T = 26.4°
Step-by-step explanation:
✔️Apply pythagorean theorem to find the length of NC:
NC = √(17.2² - 15.4²) = √58.68
NC ≈ 7.7
✔️Apply trigonometric function to find Angle T:
Reference angle = T
Hypotenuse = 17.2
Adjacent length = 15.4
Apply CAH, thus:
T ≈ 26.4°
✔️C = 180 - (90 + 26.4) (sum of triangle)
C = 63.6°
(w³+7)/w=(9w²+7)/9
(w³+7)9=(9w²+7)x
9w³+63=9w³+7x
63=7x
x=9
Answer:
B' (1, 2 )
Step-by-step explanation:
Since the centre of dilatation is the origin then multiply the coordinates of B by the scale factor.
B (4, 8 ) → B' (4 × 
, 8 × ) → B' (1, 2 )
Answer:
23
Step-by-step explanation:
First, do 28 times two, since he's getting twice as many colored pencils. You should get 56. Then you take 11, and since he has 3 sisters you multiply it by three. Then you have 33. When you get this, you need to subtract 33 from 56. You should get 23 and that's your answer.
