Answer:

<h2>1.57 cm</h2>

Step-by-step explanation:

the circle has a radius of 2.

Then

The circumference of the circle = 2πr = 2π(2) = 4π

…………………………………

Since , 45/360 = 1/8

Then, the arc is 1/8 of the entire circle.

…………………

Therefore,

the length of a 45° arc = 4π/8 = π/2 cm ≈ 1.57 cm

Contact [7]
Based on the given equation above, get the value of x first so that this value can be substituted to the second equation. Value of x can be obtained by taking the arc sin of 7/11 which gives an answer of 39.52 degrees. Substituting this value to the second equation cos (90-39.52) gives an answer equals to 7/11
