Answer:
x + (x + 55) = 180
2x =125
The angle is 62.5 degrees
Double-Check
62.5 + (62.5 + 55) = 180
125 + 55 = 180
62.5 is the smaller angle
Step-by-step explanation:
Answer:
sin∅ = 12/13
Step-by-step explanation:
use pythagorean theorem to find the missing side
a² + 5² = 13²
a² = 13² - 5²
a² = 169 - 25
a² = 144
a = 12
-----------------------------
Sin∅ = opp/hyp
sin∅ = 12/13

This problem can be looked at like a right triangle, where the hypotenuse is 750 and one leg is 450. Thus 450^2 + the length of the park^2 = 750 ^2.
202500 + the length of the park^2 = 562500
the length of the park^2 = 360000
the length of the park = 600
