Which statement is true about a right triangle?
a. the two angles other than the right angle must be total 90 degrees
b. exactly two angles must be right angles
c. one angle must measure exactly 60 degrees
d. all three sides of a right triangle must be equal to each other

Its A because all angles must equal 180 degrees

The answer is A because if it is a 45-45-90 right triangle then all angles other than the right angle (one with the box) must be 45 and 45. 45 +45= 90. 90+90= 180.

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
