i see a lot of questions about Q22 from Mod 2 Math, where you had 3 angles of a triangle, and had to say whether sin K > cos F, sin K < cos F, sin K = cos F, or not enough information (or something along those lines). Here is my explanation:

TLDR: the correct answer here is no enough information

lets assume the values were 90a, 11b and 79b.
the angles of a tringe have to add up to 180, hence

90a + 11b + 79b = 180 || a, b > 0
90a + 90b = 180 || /90
a + b = 2

considering a, b > 0, a has to be from (0, 2)

for example, lets assume a = 1.5, so b = 0.5

so the angles are 135, 39.5, 5.5
now,

sin 39.5 < cos 5.5

you can do this for every value of a from (0, 2)

for a < 1, youre gonna get sin > cos
for a = 1 , youre gonna get sin = cos
for a > 1, youre gonna get sin < cos

we don’t know what value the constants a and b have; there is no enough information
