The answer is option 2.
Step-by-step explanation:
First, you have to eliminate brackets, you have to divide -1.5 to both sides :



Next you have to solve r :




Answer:
7 )
x = 

8 )


Step-by-step explanation:
7 ) 8)
In Δ ABC In Δ XYZ
∠ C = 45° ∠ X = 60°
∠ A = 90° ∠ Y = 90°

To Find :
x = ?
y = ?
Solution:
We Know
In Δ ABC
∠ C = 45°
∠ A = 90°
∴ ∠ B = 45° ......Angle sum property of a triangle i.e 180°
∴ Δ ABC is an Isosceles Triangle
∴ AC = AB = x = 
Now appplying Trignometry identity we get

Now In Δ XYZ
∠ X = 60°
∠ Y = 90°
∴∠ Z = 30° . .....Angle sum property of a triangle i.e 180°
Now appplying Trignometry identity we get


Now,

Answer:
7.745
Step-by-step explanation:
Square root of 60 equals X.
This is a square matrix whose entries are real and rows and columns are orthogonal unit vectors.
310 / 75-5 = 4.42 or 4.4 hours. Let me know if you have any other questions.
