Equation 5x+15=180°

x=33°

Step-by-step explanation:

Angles on a straight line always add up to 180°.

Form an equation:

4x+15+x=180° (Both of the red and blue angles add up to make the straight line).

Collect like terms:

Like terms are terms with the same variables and powers.

4x+x=5x

Put it back into an equation:

5x+15=180°

To find x, you would have to do inverse operations to isolate it.

180-15=165°

5x=165°

165÷5=33° (We divide by 5 because, in algebra, when a number is next to a letter it means times and as we want the inverse we divide).

So, x=33°

Hope this helps :)

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
