If the sequence is like this, you actually don’t have to formulate a formula. You just have to formulate a principle. You just have to remember that when n is an odd number, the value would always be 1. If the n is an even number, the value would always be 0.

Answer:

b = $22.62^{o}$

Step-by-step explanation:

Since the triangle is a right angled triangle, the appropriate trigonometric function can be applied to determine the value of b.

Thus, to determine the value of b;

Sin θ = $\frac{opposite}{hypotenuse}$

Sin b = $\frac{20}{52}$

= $\frac{20}{52}$

= 0.38462

⇒ b = $Sin^{-1}$ 0.38462

= 22.6202

b = $22.62^{o}$

The measure of angle E (= b) is $22.62^{o}$ .
