The sine of any acute angle is equal to the cosine of its complement. The cosine of any acute angle is equal to the sine of its complement. of any acute angle equals its cofunction of the angle's complement.
A
C
B
Since m∠A = 22º is given, we know m∠B = 68º since there are 180º in the triangle. Since the measures of these acute angles of a right triangle add to 90º, we know these acute angles are complementary. ∠A is the complement of ∠B, and ∠B is the complement of ∠A.
If we write, m∠B = 90º - m∠A (or m∠A = 90º - m∠B ), and we substitute into the original observation, we have:
Answer:
No he wont.
Step-by-step explanation:
50% of 40=20
40+20=60
40+8=48
Michael has 48 and Susan has 60

-5+x/9 =inverse
Step-by-step explanation:
Answer:
answer maybe x^2 + 3x - 28
explanation
first of all this is how any number of such a kind shud be written
ax^2 + bx + c
so that rearrange it
7x^2 + 3x -4
but I personally would go further to put it like this
x^2 + 3x - 28
both answers are the same so but maybe one is more considered since ur qn requires standard form
in case of any misunderstanding plizzz reach out for further explanation
hope this helps
