1: Identify the angle.

The following angle is a 90.

2: Set up the equation.

x + (3x + 10) = 90

3: Combine like terms.

4x + 10 = 90

4: Solve for x.

4x + 10 = 90

-10 = - 10

Add all the similar terms
4x+10 = 90
4x = 90 -10
4x = 80
80/4= 20
x = 20

Then substitute x = 20 in to make sure it’s right (:
it is thought so don’t worry (:

Given x=5 + √16 , select the value(s) of x. -11 1 9 21

Schach [20]

Answer:

The answers would be 9 and 1.

Step-by-step explanation:

x= 5±√16 can be separated into two equations.

x=5+√16 and x=5-√16

1. 5+√16 can be solved by simplify √16, which is 4. So then it would become 5+4 which equals 9.

2. 5-√16 can be solved by simplifying √16 which is 4. So then it would become 5-4 which equals 1.

So the values of x are 9 and 1.
