The answer is d 100 tan 40 degrees
Answer:
x = -6
Step-by-step explanation:
3/ x = 4/(x-2)
Using cross products
3 (x-2) = 4x
Distribute
3x - 6 = 4x
Subtract 3x from each side
3x-3x-6 = 4x-3x
-6 =x
Answer:
A=32
Step-by-step explanation:
Area of a trapezium=1/2(a+b)h
A=1/2(6+10)4
A=1/2(16)4
divide 16 by 2
A=(8)4
open the bracket
A=32
Check/ verify
A=1/2(a+b)h
32=1/2(6+10)4
32=1/2(16)4
divide 16 by 2
32=(8)4
32=32.
I hope this hopes?
<span>we know that cos(a - b) = cos(a) cos(b) + sin(a) sin(b)
given a = π/3 and b = π/5
cos(π/3) cos(π/5) + sin(π/3) sin(π/5) = cos((π/3) - (π/5) = cos(2π/15)
hope it helps
