Find the value of x and please write how you did it.

2.4 m

Step-by-step explanation:

sin(A) = opposite/hypotenuse

Using the bigger triangle:

sin(A) = 4/5

Using the smaller triangle:

sin(A) = X/3

4/5 = X/3

X = 4/5 × 3

X = 2.4m

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
