Question

I also need help on this one too.

Answer 1

Explanation:

Solution,

Taking angle A=60° as reference angle, we have

perpendicular(p)=3

hypotenuse(h)=c

base(b)=b

Now,

Tan 60°=p/b

√3=3/b

b=3/√3

b=1.732

Again,

Sin 60°=p/h

√3/2=3/c

√3×c=3×2

√3×c=6

c=6/√3

c=3.4

Answer 2

• If A is 60 then B will be 30

`\\ \sf\longmapsto tan60=(a)/(b)`

`\\ \sf\longmapsto √(3)=(3)/(b)`

`\\ \sf\longmapsto b=(3)/(√(3))`

`\\ \sf\longmapsto b=√(3)`

`\\ \sf\longmapsto b=1.732`

Now

`\\ \sf\longmapsto a^2+b^2=c^2`

`\\ \sf\longmapsto (√(3))^2+3^2=c^2`

`\\ \sf\longmapsto c^2=9+3`

`\\ \sf\longmapsto c^2=12`

`\\ \sf\longmapsto c=3.3`
