A. Explain how you know the right triangles are similar. b. Write a ratio that is equivalent to z/x

c. Which ratios of side lengths are equal to tan(a)?

d. Explain why the values of the trigonometric ratios only depend on the angle a and not on the particular lengths x, y, 2, q. r, s.
E. If Y/Z =0.7. what is the measure of a to the nearest degree?

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
