Answer:
the first hike is going down negative(low) second hike is going up so positive (high)
Step-by-step explanation:
∠BCD = 57°
∴ ∠BDR = ∠BCD = 57° (angle that meets the chord and the tangent is equi-angular to the angle at the alternate segment)
Answer is a, 57.49.
17.42-12.60-9.62= $-4.80+62.29=57.49
I'm guessing you find the length of the hypotenuse using the pythagorean theorem.
a² + b² = c² a and b are the legs and c is the hypotenuse
15² + 8² = c²
225 + 64 = c²
289 = c²
√289 = √c²
17 = c
hope that helps, God bless!
