AB and BC are tangents to P. what is the value of x? this is really so confusing
Westkost [7]
1. Angle PAB is 90 degrees, as it is formed from the tanget to the circle at A, and the radius drawn to A. 

2. AB=BC, because tangents drawn to a circle from the same point are equal.

3. PB is Common, so by the side-side-side congruence postulate, triangles ABP and CBP are congruent. 

4. So measure of m(BPA)=x/2 and m(ABP)=73/2.

5. \frac{x}{2}+90+ \frac{73}{2}=180

\frac{x+73}{2}=90

x+73=180, x= 107 degrees.

A car-carrier trailer weighs 35,000 pounds when empty. The driver loads 7 cars on the trailer. The cars are identical except for
astraxan [27]

Answer:

Each car weighs 2,265 pounds

Step-by-step explanation:

Given that the car carrier weighs 35,000 pounds when empty, that is, without cars, and that loading 7 cars its weight is 50,855 pounds, the difference between both values implies the weight of the 7 cars together, which is determined through the following calculation:

50,855 - 35,000 = X

15.855 = X

Thus, the weight of the 7 cars together is 15,855 pounds. In turn, the weight of each particular car is determined from the following division:

15.855 / 7 = X

2,265 = X

Therefore, each car weighs about 2,265 pounds.

Lostsunrise [7]

Answer:

2pi/3 has the same Sin, Cos, & Tan as pi/3 in QI except for the SIGNS.

2pi/3 is in QII so Cos is negative and Tangent is negative, Sine is still positive.

Sin 2pi/3 = √(3) / 2

Cos 2pi/3 = -1/2

Tan 2pi/3 = -√3
