Suppose p is the predicate de ned by p(x; y) = x is friends with y, where
x and y are people. (no one is considered to be friends with themselves.)
translate the formal expression 8x9y9z(y 6= z ^ p(x; y) ^ p(x; z)) into
english.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
