1/4(8x+56)=20
1/4(8x)+1/4(56)=20
2x+14=20
2x=20-14
2x=6
X=3
In the middle:
x-coordinate= {7-(-1)}/2= 4
y-coordinate= (8-2)/2= 3
So centre is (4,3)
Look it up on the internet youll find the answer there i am only learining about adding integers right now
Answer:
Step-by-step explanation:
I believe A is non-linear
Image is very dark. I guess you are asking the value of x. If so:
The mentioned angle is aright angle that is divided into 2 smaller angles, one of 69° and the other of (2x°-1). Hence
69° + 2x°- 1° = 90°
2x° = 90° + 1° - 69°
2x° = 22°
And x = 11°
If x = 11,then 2x - 1 = 21° (missing angle)
