Which pair of angles has congruent values for the sin xº and the cos yº? 35°; 55°
35°; 145°
O35°; 70°
O35°; 35°

A: 35°, 55°

Step-by-step explanation:

For the pair of angles has congruent, we have; x + y = 90°

It also means that; cos x = sin y.

Looking at the options, the only one where the angles sum up to 90° is 35°; 55°

35°, 55°

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

answer: y=4000x+14000
