We know that
in a right triangle
if sin A= cos B
then
angle A and angle B are complementary angles
so A+B=90
therefore
(7x-15)+(3x+5)=90-----> 10x-10=90----> 10x=100----> x=10°
so
7x-15------> 7*10-15----> 55°
3x+5------> 3*10+5----> 35°
we know that
<span>β < α
therefore
the answer is
</span>β =35°
<span>α=55</span>°
Answer:
Step-by-step explanation:
12x^2y / 4xy = 3x
So 4xy is the highest common factor.

Answer:
Step-by-step explanation:
The first digit is 9
the 2nd one from the right = 2
So far what you have is

941,121
There seems to be a second 4 implied. What is it? I'll edit if you get it to me in the next hour.
