\huge\text{Hey there!}

\large\text{If x = 4 and f(x) = y}

\mathsf{y = 4^2 + 5(4)}

\mathsf{4^2 = 4 \times 4 = 16}

\mathsf{y = 16 + 5(4)}

\mathsf{5(4) = 20}

\mathsf{y = 16 + 20}

\mathsf{36= 20 + 16}

\mathsf{y = 36}

\boxed{\boxed{\mathsf{Answer: \bf{y = 36}}}}\huge\checkmark

Given that ∠Ф = 180°, determine the numerical value of this function.
Rudiy27

Answer:

The answer to your question is 3. 0

Step-by-step explanation:

For an angle of 180°:

- hypotenuse = 1

- Adjacent side = 1

- Opposite side = 0

Then, sin Ф = \frac{Opposite side}{Hypotenuse}

         sin 180° = \frac{0}{1}

         sin 180° = 0

How can you use the properties of operations to evaluate<br> this expression?<br> 18 + 4(28)
nirvana33 [79]

Answer:

Well on of the properties states that unless there are parenthesis, you multiply and divide first then you add and subtract. So, first we multiply 28*4 and that leaves use with 112, now if there is no more multiplication, division, or parentheses, and there's not. We can continue all we do is add 18+112 and we get our answer of 130.

❥\Large\pmb{ \underline {\tt Answer}}

So we can only find x if other two angles of triangle is given.

In angle B as u can see boxed shape angle is there then it probably means it's a 90° angle.

We know sum of angles of triangle = 180°

{Reson :-

There's a formula to fund sum of angles of figure

  • (n-2) × 180
  • (3 -2) × 180
  • 1 × 180
  • 180°

}

Now Let's proceed

\boxed{ \rm Side_1+Side_2+Side_3 = 180\degree}

Fill all the given values

\dashrightarrow \tt 90 \degree + 55 \degree + c = 180 \degree

\\  \\

\dashrightarrow \tt 145\degree + c = 180 \degree

\\  \\

\dashrightarrow \tt  c = 180  \degree - 145\degree

\\  \\

\dashrightarrow \tt  c = 35\degree

\\  \\

Value of x = 35°
