Find the measure of the indicated angle to the nearest degree
1 answer:
Answer:
32°
Step-by-step explanation:
use this formula :
Now you want to get the angle be x, so the opposite side is 28 and hypotenuse is 53. Putting in the formula we get:
Sin(x) = 28/53
Sin(x)= 0.5283018868
So to find x just do Sin^-1
x = Sin^-1 (0.5283018868)
you get 31.8907918, ok so we just want the nearest degree and if we do that we get 32˚
if you put them into your calculator you will get 32˚ as your answer

Answer:
4
Step-by-step explanation:
The ratio of green : pink = 32 : 56 = 4 : 7
After 7 pink are given away, then
ratio = ? : 49 = 4 : 7 ← ratio has to be the same
Using proportion
=
( cross- multiply )
7? = 196 ( divide both sides by 7 )
? = 28
Thus the ratio = 28 : 49 = 4 : 7
Thus 32 - 28 = 4 green should be given
