Answer:
13.5
Step-by-step explanation:
Using sine rule
Tan25 = AC/AB = AC/29
AC = 29 × Tan 25 = 29 × 0.45 = 13.5229220865
Answer:
Step-by-step explanation:
The formula for determining the the area of a sector is expressed as
Area of Sector = θ/360 × πr²
Where
θ represents the central angle.
π is a constant whose value is 3.14
r represents the radius of the circle.
From the information given,
The central angle is π/7 radian. Converting to degrees, it becomes
π/7 × 180/π = 180/7 = 25.714 degrees.
Area of sector = 77 square meters
Therefore
77 = 25.714/360 × 3.14 × r²
77 = 0.2243r²
r² = 77/0.2243 = 343.29
r = √343.29 = 18.53 meters

---------------------------
= (3/8) (16x + - 24)
=(3/8) (16x) +(3/8)(-24)
=6x - 9
