Given that
∠ABC and ∠CBD are complementary
Sum of complementary angle = 90°
⇒ m∠ABC + m∠CBD = 90°
⇒ 25° + m∠CBD = 90° [ Given that m∠ABC = 25°]
⇒ m∠CBD = 90° - 25°
⇒ m∠CBD = 65°
Hence proved
Answer: 5
Step by step: a=2 and b=3 so it’s 2+3 which equals 5
Step-by-step explanation:
Create a right triangle with the hypotenuse = 2400in (same as 200ft) and angle from horizontal =15 degrees
you can create the equation to find the opposite line (y-value)
2400sin(15) =
621 in
