Step-by-step explanation:
angle A and Angle D are congruent. as are Angle C and Angle F.
because you have two pairs of congruent angles this proves the triangles are similar using AA Theorem.
I couldn't read the 3rd question. if you post as a comment I can look at it better.
Answer:
76
Step-by-step explanation:
a10=-5+9(10-1)=-5+9×9=-5+81=76
A whole number is a whole positive number (0, 1, 2,3 ,4....)
Integers are any whole number (negative or positive)
The answer is false
because an integer like - 4 is not a whole number
Answer:
see explanation
Step-by-step explanation:
To show f and g are inverses we require to show that
f(g(x)) = x and g(f(x)) = x
f(g(x))
= f(6x - 4)
=
=
= x
-----------------------------------------------------------------------------
g(f(x))
= g(
)
= ( 6 ×
) - 4
= x + 4 - 4 = x
-------------------------------------------------
Hence f and g are inverses
Answer:
Sin(theta) = 3/5
Step-by-step explanation:
Remark
The Sin(theta) = opposite / hypotenuse
The opposite side is not defining the angle. The hypotenuse is the longest side of a right triangle.
In this case the opposite is 3
The hypotenuse = 5
Answer: Sin(theta) = 3/5
