b. 520/800=13/20
Answer:
(x-4)²
Step-by-step explanation:
(x-4)²
(x-4)(x-4)
x(x-4)-4(x-4)
x²-4x-4x+16
x²-8x+16
Answer:
The two angles are 85 and 95 degrees
Step-by-step explanation:
Supplementary angles add to 180
Let x be one angle
The supplement is 10 less, ( x-10)
They add to 180
x+ ( x-10) = 180
2x -10 = 180
Add 10 to each side
2x-10+10 =180-10
2x= 190
Divide by 2
2x/2 =190/2
x=95
The other angle is 95-10 = 85
The two angles are 85 and 95 degrees
130 degrees. The whole line is supposed to equal 180 so 180-50 is 130
