4×22/7×2.6^2=85.0cm
Answer:
Step-by-step explanation:
<u>Use midpoint formula</u>
- x = (x₁ + x₂)/2
- y = (y₁ + y₂)/2
#3
Endpoints (0, 0) and (6, 8)
<u>Midpoint has coordinates:</u>
Correct choice is C
#4
Endpoints (-5, 3) and (3, 15)
<u>Midpoint has coordinates:</u>
- x = (-5 + 3)/2 = -1, y = (3 + 15)/2 = 9
- Point is (-1, 9)
Correct choice is B
Uhhhhhhhhhhhhhhhhhhhuhhhhhhhhhhhhhh
Tangent (angle) = opposite / adjacent
tangent (angle) = 8,749 / 675
tangent (angle) = 13
arc tangent (13) = 85.601 Degrees
answer is D
