Answer: SOH CAH TOA Tan C= 11/22= 1/2 So Tan C= 1/2
Sin B= x/17
Step-by-step explanation:
SOH CAH TOA = S=o/h C=a/h T=o/a.
I love trig ratios!
Hope this helped.
Solution :
2a + 2b = 7 ...1)
4a + 3b = 12 ...2)
In equation, 1)
a = (7 - 2b)/2 ...3)
Putting value of a in equation 2) we get :
4 × (7 - 2b)/2 + 3b = 12
2( 7 - 2b ) + 3b = 12
14 - 4b + 3b = 12
b = 2
Putting value of b in 3) we get :
a = ( 7 - 2×2)/2
a = 3/2 = 1.5
Now,
2x - 3y = 16 ...5)
x + 2y = -6 ...6)
x = -6 - 2y
Putting above value of x in eq 5) , we get :
2( -6 - 2y ) - 3y = 16
-12 - 4y - 3y = 16
7y = -28
y = -4
x = -6 - ( 2× -4 )
x = 2
Hence, this is the required solution.
A (5, 4) and B( 5, -2) is 6 units
E(-2, -1) and F(-2, -5) is 4 units
G(3, -5) and H(6, -5) is 3 units
C(-4, 1) and D(1, 1) is 5 units
