D. how much insurance you will carry
Answer:
X= -3;
Y=78
Step-by-step explanation:
A: X+Y=75
B: 10X+Y=48
B-A: (10X+Y)-(X+Y)=48-75
10X+Y-X-Y= - 27
9X=-27
X= -3;
Now
A is : -3+Y=75
Y=75+3=78
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°
