Answer:
x = 50°
x = 70°
Step-by-step explanation:
A right angle is indicated by a small box.
The angles shown are right angles = 90° each. Therefore:
✔️x + 40° = 90°
Subtract 40° from each side
x = 90° - 40°
x = 50°
✔️x + 20° = 90°
Subtract 20° from each side
x = 90° - 20°
x = 70°

<em>Product, factors, polynomial, distributive property
</em>
For this case we must find the product of two factors of a polynomial. To do this, we must apply the distributive property, which states: ![a (b + c) = ab + ac.](https://tex.z-dn.net/?f=a%20%28b%20%2B%20c%29%20%3D%20ab%20%2B%20ac.)
So:
![2x (x - 4) = 2x * x-2x * 4\\2x (x - 4) = 2x ^ 2-8x](https://tex.z-dn.net/?f=2x%20%28x%20-%204%29%20%3D%202x%20%2A%20x-2x%20%2A%204%5C%5C2x%20%28x%20-%204%29%20%3D%202x%20%5E%202-8x)
Thus, the product of
is: ![2x ^ 2-8x](https://tex.z-dn.net/?f=2x%20%5E%202-8x)
Answer:
The product of
is: ![2x ^ 2-8x](https://tex.z-dn.net/?f=2x%20%5E%202-8x)
We make use of
to solve for y, when you know x and z
<h3>How to solve for y?</h3>
The expression is given as:
x^y = z
The above expression is an exponential expression.
Start by taking the logarithm of both sides
y log(x) = log(z)
Divide both sides by log(x)
![y = \log_x(z)](https://tex.z-dn.net/?f=y%20%3D%20%5Clog_x%28z%29)
Hence, we make use of
to solve for y, when you know x and z
