By geometry, there is a relationship between the tangent PA and the segments PB and PE, namely
PA^2=PB*PE
so
PE=PA^2/PA=6^2/4=9
BE=PB-PE=9-4=5
Answer:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
The measure of angle 2 is 
Explanation:
Given that 
and 
are complementary angles.
Also, the measure of angle 1 is 
We need to determine the measure of
Since, we know that the complementary angles add up to 90°, then the angles and add up to 90°.
Thus, we have,
Substituting the value of in the above expression, we have,
Subtracting both sides by 76°, we get,
Simplifying, we have,
Thus, the measure of angle 2 is
1/8 because if u simplify your answer..to have 4 as the denominator it would work easier
The answer is D. 5 hours, due to the fact that there football field together, so adding there times they had done the football field individually, Tiana,3 hours, and Jacob 2 hours 2h+3h=5hours. hope i helped.
