Answer:
Step-by-step explanation:
Given that two tangents to a circle intersect at a point B outside the circle
A and C are points of contact.
By theorem on circles we have angle ABC is equal to 1/2 the difference of intercepted arcs.
Angle of minor arc =110 and hence major arc
Difference =
Measure of angle ABC 1/2 of 140 = 70 degrees.

Step-by-step explanation:
Answer:
1.
by using Pythagoras theorem
h²=p²+b²
h²=12²+40²
h=√1744
AB=42
2.
x+48°+90°=180°{sum of interior angle of triangle}
x=180°-138°
x=42°
Step 1
find the area of the wall
area of the wall=10*20------> 200 ft²
step 2
if 200 ft²---------------------> contains 1 ton of briks
1800 ft²--------------------> x
x=1800/200------> x=18/2-----> x=9 tons
the answer is
9 tons
It's not, because it doesn't go through the origin (0,0)
