Two angles are supplementary. The measure of the larger angle is 4 more than 3 times the measure of the smaller angle: Find the measures of both angles. Provide your answer below:

1.Inc que ( \( \left.\frac{1}{3}\right) \)

Question 4 Events A and B are such that \( P(A)=0,21 \) and \( P(A \cup B)=0,89 \). Let's assume that events \( A \) and \( B \) are independent, determine \( P(B) \).

9. The Shanghai Maglev Train is ane of the fastest trains in the world, traveling about 2,144 miles in 8 hours. a. How many miles does it travel in one hour?

b) \( \frac{1}{5^{4}} \cdot \frac{1}{5^{-3}} \cdot 5 \)

Find a value of \( \theta \) in the interval \( \left[0^{\circ}, 90^{\circ}\right] \) that satisfies the given statement. \( \cos \theta=0.85473615 \) \( \theta \approx \square^{\circ} \) (Simplify your answer. Type an integer or a decimal. Round to six decimal places if needed.)
