Use a calculator to find the values of the inverse trigonometric functions. Round to the nearest degree. sin–1 (two-thirds) = ° tan–1(4) = ° cos–1(0.1) = °

sin-1(2/3)=42 tan-1(4)=76 cos-1(0.1)=84

Step-by-step explanation:

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
