Question

Find the value of x in each case:

Answer 1

Answer:

Step-by-step explanation:

Sum of 3 angles of triangle= 180

147 + 4x + x = 180

147 +5x = 180

5x = 180 - 147

5x = 33

x = 33/5

x = 6•6 (Answer)

Answer 2

Answer:

X = 11

Step-by-step explanation:

To solve this, we need to find all the angles within the triangle. We know one angle (f) is 33 degrees because 147 + f = 180 = f = 33. Next we need to set up two more formulas to solve for x:

4x + y = 180

x + y + 33 = 180 => x + y = 147

Next, we can isolate one of the variables in one of the formulas and plug it back into the other:

x + y = 147 => y = 147 - x

4x + y = 180 => 4x + 147 - x = 180 => 3x + 147 = 180 => 3x = 33 => x = 11

I hope this helps!
