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:
x = 7 / 2, y = - 5 / 2
Step-by-step explanation:
3x + y = 8 ------> equation 1
3 ( 3x + y = 8 )
9x + 3y = 24 ------> equation 2
x - 3y = 11 ------> equation 3
Add equations 2 & 3,
9x + 3y = 24
x - 3y = 11
_________
10x + 0 = 35
10x = 35
x = 35 / 10
x = 3.5
Substitute x = 3.5 in equation 1,
3x + y = 8
3 ( 3.5 ) + y = 8
10.5 + y = 8
y = 8 - 10.5
y = - 2.5
x = 3.5
= 35 / 10
x = 7 / 2
y = - 2.5
= - 25 / 10
y = - 5 / 2
