Sin x* = 40/50

Using arcsine, we can find the measure of the angle.

x = Sin^-1(0.8)

x = 53.13010235

The missing angle is equal to 53.13010235

(I think the answer your homework is looking for is 4/5)

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
