Answer:
165 cm.
Step-by-step explanation:
Let h be the height of Cody on the first day of school last year.
We have been given that Cody was 165 cm tall on the first day of school this year, which was 10% taller than he was on the first day of school last year.
To find the height of Cody on the first day of school last year, we need to find h such that h plus 10% of h equals 165. We can represent this information in an equation as:
Let us divide both sides of our equation by 1.10.
Therefore, Cody was 150 cm tall on the first day of school last year.
Answer:
1) x ≅ 51.34°
2) y ≅ 38.66°
Step-by-step explanation:
In the right triangle given in the figure
∵ The triangle has a right angle
∴ Angles x and y are acute angles and the sum of their measures is 90°
→ By using the trigonometry function tan
∵ tan(x) = opposite side to x/adjacent side to x
∵ The opposite side to x = 10
∵ The adjacent side to x = 8
→ Substitute them in the rule above
∴ tan(x) = =
→ Use the inverse of tan to find x
∵ x = (
)
∴ x = 51.34019175
∴ x ≅ 51.34°
∵ x + y = 90°
∴ 51.34 + y = 90
→ Subtract 51.34 from both sides
∴ y ≅ 38.66°
