The value of Sin(a) suppose that Cos B = 0.68 in which case, a + B = 90° is; 0.68.
<h3>Trigonometry</h3>
First, when we have two angles, whose sum equals, 90°.
In essence, Since the algebraic sum of angles A and B is 90°;
By trigonometric identity;
Where; (90 - A) = B.
Therefore; Sin A = Cos B = 0.68.

Answer:
(0,7/6)
Step-by-step explanation:
Opposite angles of an isosceles trapezoid add up to 180.
(That graphic is very blurry. I hope I can read it correctly.)
14x + 3x + 10 = 180
17x = 170
x = 10
Answer: 10% of the beads are plastic.
Step-by-step explanation: 10 out of 100 beads are plastic, bc 90 + 10 = 100.
10/100 = ?/100
Nvm, this easy, it's the same thing so 10% of the beads are plastic.
