Answer:
Y= 21x+10.25
Step-by-step explanation:
(1,31.25) (0,10.25)
Slope= 21
21X-0=y-10.25
Y= 21x+10.25

Answer:
the given triangles are right triangles which is enough to prove them 'similar'
but not congruent.
Answer:
Angle y and Angle x are complementary angles
Step-by-step explanation:
we know that
If
sin(y°)=cos(x°)
then
Angle y and Angle x are complementary angles
so
∠y+∠x=90°
∠x=90°-∠y
sin(y°)=cos(90°-y°)
therefore
The sine of an angle is equal to the cosine of its complementary angle
