Answer is 120 because all of the angles add up to 180. 180-26-34= Y
Answer:
x = - 
Step-by-step explanation:
A theorem states that (using letters from in this problem) that:
AB * BE = DC * CE
Applying that you can find that:
11 ( x + 1 ) = 1 ( x + 4 )
11 x + 11 = x + 4
11 x + 11 - x = x + 4 - x
10 x + 11 = 4
10 x + 11 - 11 = 4 - 11
10 x = -7
10 x / 10 = -7 / 10
x = - 
Answer:
(5x + 7y)² = 25x² + 70xy + 49y²
Step-by-step explanation:
(5x + 7y)² = 25x² + 70xy + 49y²
Because,
(5x + b)² = (5x)² + 2(5x)(b) + b²
2(5x)(b) = 70xy
b = 7y
b² = (7y)² = 49y²
Answer:
The answer would be 4
Step-by-step explanation:
you can’t have repeating numbers in a function.
Answer:
Disagree
Step-by-step explanation:
Remember rotating 90 degrees means (y,-x)
A= (1,2)
A'= (2,-1)
So it is disagreed.
Hope this help :)
