Question

Ouestion 10 part c
Evaluate the value of x and y

Answer 1

Answer:

In rt.angled triangleADC,

Cos60degree=base/hypotenuse=x/10m

or,1/2=x/10

or,x=5 m

Now ,In rt.angled triangleBDC,

Sin ydegree=perpendicular/hypotenuse

or, ydegree=x/5root2 m

or,ydegree=5/5root2 m(since x=5 m)

or,y degree=1/root2 m

or,y degree=30degree

Step-by-step explanation:

Answer =value of x is 5 and value of y is 30 degree
