Sum of complementary angles = 90
so
5x + 35 = 90
5x = 90 -35
5x = 55
x = 11
answer is A.
x = 11
The coordinates for point a are (-3,5)
The first point tells you the x value and the second tells the y value
Answer:
The value of n is 30.25.
Step-by-step explanation:
The given expression is
....(1)
The perfect square trinomial are defined as
.....(2)
On comparing (1) and (2), we get


The given expression is perfect square trinomial if




Therefore the value of n is 30.25.
Y=5x-2. Substitute into the second
-3x+6(5x-2)=-12
-3x+30x-12=-12
The -12 cancel
27x=0
x=0
y=-2
check in the second equation
0+6(-2)=-12
