Question

(a) Find x and y from the adjoining figure.
​

Answer 1

Answer:

x=3cm

y=5cm I think but not sure

Answer 2

Step-by-step explanation:

By Pythagoras theorem

Cos theta = Adjacent side/ Hypotenuse

Here theta =60°

Cos 60° = 4 /y

1 / 2 = 4 /y

y = 2cm

Sin theta = Opposite side / Hypotenuse

Sin 60° = x / y

√3 / 2 = x /2

x = √3 cm
