Aleks [24]

Answer:

r = \frac{1}{2}

Step-by-step explanation:

Solve for x and why please using these!!!
krok68 [10]

Answer:

x = 40

y = 5

Step-by-step explanation:

4x = 2x+80\\2x = 80\\x = 40

Edit: Solve for Y

A straight line is 180 degrees so one side (the x side) is 160°, The Y side is 20, and  you can work backwards by -

8y - 20 = 20\\8y = 40\\y = 5
