It’s B
You need to use the Pythagorean theorem which is a squared + b squared = c squared
So a^2+4^2=5^2
Simplified that would be a^2 + 16 = 25
Subtract 16 from both sides
A^2=9
And the square root of nine is 3
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
Answer:
y= -0.3x - 5.6
Step-by-step explanation:
m= (-5)-(-8)/(-2)-8
m= -0.3
y=mx+c
-8= -0.3(8)+c
-8= -2.4 +c
-8+2.4=c
c= -28/5
y= -0.3x - 5.6
Answer:
I'm not sure about the question, but the one thing that is needed for a function is the "=" sign. Only option c has an equals sign. The others, as written, are just expressions, not equations.
Step-by-step explanation:
Even option c doesn't conform to the y = mx + b form, but it is far ahead of the other options.
