<h3>
Answer: C) 4/8 = 0.5</h3>
=========================================================
Explanation:
The sine ratio involves the opposite over hypotenuse.
With respect to reference angle J, the opposite leg is the one furthest from the angle. So the opposite side is KL = 4. The hypotenuse is always the longest side, always opposite the 90 degree angle, so LJ = 8 is the hypotenuse.
sin(angle) = opposite/hypotenuse
sin(J) = KL/LJ
sin(J) = 4/8
sin(J) = 0.5
You have to multiply 3x3 since it says 3^2 then subtract 9 from 10 you get 1. Then you have to diving 8x and 1 and you get 1/8
It would be 2.5E-2 or with the power of 10 it would be 2.5 x 10^-2
Answer:
84
Step-by-step explanation:
reach triangle area is 1/2bh so
1/2(6)(4) = 12
there are 4 of them so
12x 4 = 48
then the square is 6x6 = 36
add the square to the triangle totals
48+38 = 84
