Me asap how to understand measuring angles

this depends. you can measure angles in real life with a protractor or just use your eye. let us start with the protractor. place the midpoint of a protractor on the vertex of the angle and make sure it lines up to 0. on the other side read the degrees (make sure everything aligns). without a protractor you can use the Sine Formula and measure the lines.

You would need a protractor for this or you can measure a line segment and use the SOH-CAH-TOA if you have side lengths.

Sin = opp/hyp

Cos= adj/hyp

Tan = opp/adj

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
