Find the area of the shape shown below using the screenshot i took

For this case we have that the figure shown is composed of three triangles and a square. By definition, the area of a triangle is given by:

Where:

b: It's the base

h: It's the height

We have 3 triangles, then the sum of their areas will be:

On the other hand, the area of a square is given by:

Where:

l: It's the side of the square

According to the figure we have:

So, the total area is:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
