12)  x = 100°, y = 80° and z = 160°

13) x = 65°

Solution:

Question 12:

If a tangent and a chord intersect at a point on a circle, then the measure of each angle formed is one half of the intercepted arc.

⇒ x = 100°

Sum of the adjacent angles in a straight line is 180°.

x + y = 180°

100° + y = 180°

Subtract 100° from both sides, we get

y = 80°

By the above mentioned theorem,

Multiply by 2 on both sides, we get

⇒ 160° = z

Therefore, x = 100°, y = 80° and z = 160°.

Question 13:

If two chords intersects in the interior of the circle, then the measure of each angle is one half the sum of the measures of the arcs intercepted by the angle and its vertical angle.

⇒ ∠x = 65°

Therefore x = 65°.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

darn right!
