Sum of interior angles of a triangle = 180°
x+40+30= 180°
x+ 70=180
x= 180-70
x= 110°
Answer: The third one
Explanation: the numbers in the x column will never repeat.
Well, 0.90 is actually equal to 0.9. It is less than 0.91 and equal to 0.9 so that means it is not correct.
I hope this helps:)
Area 1st rectangle = 10 * 7 = 70 cm^2
length of 2nd rectangle is 2*7 = 14 cm
Area 2nd = 10 * 14 = 140 cm^2
140/70 = 2
The 2nd triangle was twice as big as the 1st. Answer A
Answer:
First, let's move all terms to one side,
When given this form (ax^2+bx+c=0), there will be two solutions at the end.
1) 
2) 
where, a=1, b=-8, c=6
