Triangle JKL rotated 270ﾟ counter clockwise about the origin to form triangle J'K'L'what is the Y coordinate of point J'

step-by-step explanation:

where is the questions

the answer is b.)

< 1=< 2

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
