Answer:
x = 4, y = 9
Step-by-step explanation:
The angles in a square are right, that is 90°
The diagonals bisect the angles , then
6x + 21 = 45 ( subtract 21 from both sides )
6x = 24 ( divide both sides by 6 )
x = 4
------------------------------------------------
The sides of a square are congruent , then
10y - 29 = 5y + 16 ( subtract 5y from both sides )
5y - 29 = 16 ( add 29 to both sides )
5y = 45 ( divide both sides by 5 )
y = 9
y = -2 and x= 3
Graph is attached below. Black line is the graph of y=-2
Blue line is the graph of x=3
Whenever we get equation like x = something, in that case slope is always undefined
Whenever we get equation like y = something, in that case slope is always 0
y = -2 and x= 3
For x=3, the slope is undefined.
The graph of x=3 is a vertical line at 3 on x. The x intercept is 3 and there is no y intercept.
For y=-2, the slope is 0
The graph of y=-2 is a horizontal line at -2 on y. The y intercept is -2 and there is no x intercept.
Answer:
y=15
Step-by-step explanation:
Because of the exterior angle theorem angle A plus angle b or equal to 146.
so you set 5y+3+4y+8=146 and solve
5y+3+4y+8=146
9y+11=146
9y=135
y=15
