Answer:
It is pi/2
Step-by-step explanation:
A) add the two elevations together:
6900 + 8100 = 15,000 meters.
B) Divide the total distance by 2:
15,000 / 2 = 7,500 meters.
Because the distance to the halfway point is larger than the elevation of Ojos del Salado, the elevation would be below seal level.
C Add the halfway point from part B to the lowest elevation:
-8100 + 7500 = -600 meters
Answer:
40/41
Step-by-step explanation:
tanB=opposite length/adjacent length
tanB=40/41
The intersection of two planes is a line. :) Hope it works.
Answer:
y = 12
Step-by-step explanation:
∵ m∠ABC = 40
∵ BD ray is the bisector of ∠ABC
∴ m∠ABD = m∠CBD = 20
In 2 Δ BAD and BCD:
∵ m∠BAD = m∠BCD = 90°
∵ m∠ABD = m∠CBD = 20°
∵ BD is a common side in the two triangles
∴ ΔABD congruent to ΔCBD⇒(AAS)
∴ AD = CD
∴ 3y + 6 = 5y - 18
∴ 5y - 3y = 6 + 18
∴ 2y = 24
∴ y = 24/2 = 12
