Answer:
D
Step-by-step explanation:
The 2 lines intersect at (1, 5)
That's of course the sum angle formula for sine
sin(a+b) = sin a cos b + cos a sin b
We have a=20° b=40°
sin 20° cos 40° + cos 20° sin 40°
= sin(20°+40°)
= sin(60°)
= √3/2
Answer: √3/2
Answer:
112
Step-by-step explanation:
12 square= 144
6 squared =36
144-36=112
Answer:
Number of small boxes is 50 and number of big boxes is 60
Step-by-step explanation:
let the number of small box represent x and the number of big box represent y
Hence total number of boxes = x + y = 110 ......................Eqn1
Total weight of boxes = 30x + 55y = 4800----------------Eqn2
Solving both equations simultaneously
From Eqn1, x = 110-y, substitute it into equation 2
Hence, 4800 = 30(110-y) + 55y
1500 = 25y
y = 60
X = 110 - 60 = 50
Number of small boxes is 50 and number of big boxes is 60
