Answer:
m(arc ZWY) = 305°
Step-by-step explanation:
8). Formula for the angle formed outside the circle by the intersection of two tangents or two secants is,
Angle formed by two tangents =
=
=
= 40°
9). Following the same rule as above,
Angle formed between two tangents =
125 =
250 =
250 = m(arc ZWY) - 55
m(arc ZWY) = 305°
Therefore, measure of arc ZWY = 305° will be the answer.
10). m(arc BAC) =
=
=
= 74°
Answer:
x+
y+5=0
Step-by-step explanation:
the intersection of x-2y=0 and 3x+y+5 is (;
)
=> the line : x+
y+5=0
