To find area you multiply the height and width so which ever are the height and width out of those numbers you multiply them together
The answer to this question is the mean increases by 3.
Step-by-step explanation:
a)
82+OCE=90°{ tangent}
0CE=8°
OCE=OEC (base angle of isosceles triangle r equal}
8+8+a=180°(sum of angle of triangle)
a=180-16
a=164°
b)d+BEC=180°
BEC=122°
BEO=BEC-OEC
b=114°
