10 point! ! not b, i already tried. which relationship is always correct for the angles p, q, and r of triangle abc? a p + r = q b p + q + r = 180 degrees c p + q + r = 90 degrees d q + r = p

The answer is D. q+r=p

I think its D. Its the only one that makes sense

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
