Answer:
∠B = 60°
a = 4.0 units
b = 6.9 units
Step-by-step explanation:
The triangle is right angled. The sum of all angles of a triangle is equal to 180 degrees.
The 3 angles are 90, 30 , ∠B .
<em>
</em>
Thus, B = 180 - 120 = 60 degrees
by trigonometry,
sin(30) =
= 0.5
a = (8)(0.5) = 4 units
Also,
cos(30) =
= 0.866
b = (8)(0.866)= 6.928

Answer:
no solution
Step-by-step explanation:
3(2x + 2) - 3x = 6 + 3x
6x + 6 - 3x = 6 + 3x
6x - 3x = 3x
3x + 6 = 6 + 3x
the answer would be
no solution
