Sum of interior angles in a pentagon=540°
148+112+2x+2x+10+90=540
360+4x=540
4x=540-360
4x=180
x=180/4
x=45°
20+64=84 40+44=84 74+10=84 30+54=84
That means the same as 3-17 so the answer is -14
Answer:
The answer is 10
Step-by-step explanation: You multiply the 2 times twenty to get 40 then multiply the 2 times 2x to get 4x then subtract fourty from both sides and you will get fourty and then divide so 40 divided by 4x equals 10.
75 - 75 = 0, therefore, your answer is equal to zero
