Step-by-step explanation:
ΔAOC is an isosceles triangle as OC = OA ----> RADIUS
42 + 42 + ∠AOC = 180 {Angle sum property}
84 + ∠AOC = 180
∠AOC = 180 - 84
∠AOC = 96°
y = 96/2 {Central angle theorem}
y = 48° ------------(I)
∠B + ∠D = 180 {sum of opposite angles of Cyclic Quadrilateral}
x + y = 180
x + 48 = 180 {from (I) }
x = 180 - 48
x = 132°
im not going to give u the answer but all you do is
step by step :
#1. D2- (-6*2),(0*2)=(-12,0)
(3*2), (-9*2)= (6,-18)
(12*2),(4*2)=( 24,8)
Answer:
∠c' and ∠c'' are complementary angles
Step-by-step explanation:
Since form a straight angle, then
then they are supplementary angles.
Since the is perpendicular and bisects ∠C
∠c' and ∠c'' are complementary angles
