I’ve tried calculating it on my own but I’m not getting a degree even close to the answers?

Below

Step-by-step explanation:

You need to use SOH CAH TOA to find theta.

Looking at the triangle, we have the opposite side which is 9 and the adjacent side which is 10. This means you have to use Tangent to find theta.

Tan θ = opposite/adjacent

Tan θ = 9 / 10

       θ = tan inverse ( 9 / 10 )

       θ = 41.98

       θ = 42 degrees

i think 1: 2

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
