Answer:

Y = 32.7°

Step-by-step explanation:

We will apply the Cosine law in the given triangle XYZ,

x = 90 ft

y = 55 ft

z = 50 ft

We have to find the measure of angle Y.

y² = x² + z² - 2xzCosY

(55)² = (90)² + (50)² - 2(90)(50)cosY

3025 = 8100 + 2500 - 9000.cosY

9000.cosY = 10600 - 3025

cosY = \frac{7575}{9000}

        = 0.84167

Y = \text{cos}^{-1}(0.84167)

Y = 32.68 ≈ 32.7°

Therefore, measure of angle Y = 32.7°

The button on Carey's jacket has a diameter of 8 millimeters. What is the button's circumference?
Ahat [919]

Answer:

25.12 millimeters is your answer.

Step-by-step explanation:

Circumference can be solved by using the equation:

c = 2πr or c = πd

Note that diameter (d) is equal to 8. Plug in 8 for d.

c = (8)(π)

Also note that π = 3.14. Multiply

c = (8)(3.14)

c = 25.12 millimeters.

25.12 millimeters is your answer.
