Answer:
yes, no, no
Step-by-step explanation:
The triangle will be a right triangle if the sum of the squares of the two short sides, less the square of the long side, is zero. (This is what the Pythagorean theorem tells you.) The angle where the radius meets the circle must be a right angle if the line is to be a tangent.
__
a) 3^2 +4^2 -5^2 = 9 + 16 -25 = 0 . . . . AB is a tangent
__
b) 9^2 +15^2 -18^2 = 81 +225 -324 = -18 . . . . AB is not a tangent
__
c) 10^2 +48^2 -52^2 = 100 +2304 -2704 = -300 . . . . AB is not a tangent
Answer:
C) 1/2(15 +23)(9)
Step-by-step explanation:
The formula for the area of a trapezoid in terms of base lengths b1 and b2 and height h is ...
... A = 1/2(b1 +b2)h
Substituting the values shown in the figure, this becomes ...
... A = 1/2(15 +23)(9) . . . . . matches selection C
Answer:
if that is the ratio the fraction would be 8/14 but if we were to simplify this fraction it would be 4/7
