Answer:
Heyy
Step-by-step explanation:
△ABC is a right angled triangle and right angle at B
sinA=
AC
BC
, cosA=
AC
AB
⟹sinA+cosA=
AC
BC
+
AC
AB
=
AC
BC+AB
[We know that sum of two sides of a triangle is greater than the third side]
⟹sinA+cosA>
AC
AC
=1
Hence, sinA+cosA>1
There are no real roots for a negative number, so -81 has no real roots, if the number is 81 however, then the tow roots are 9
Answer:
5/6
Step-by-step explanation:
4,5,6- Numbers greater than 3
2,3- Prime numbers
Sample space={1,2,3,4,5,6}
P(E)=5/6
Answer:
It’s 4.24 but does it need to be rounded?
Step-by-step explanation:
<span>I believe the answer is 60.75pi, calculated as follows:</span>
Area of Circle: (9 * 9) * pi = 81pi
Area of Shaded Area = (90 / 360) * 81p = 20.25pi
81pi - 20.25pi = 60.75pi
