Answer:
x = 12
Step-by-step explanation:
the two equations shown should add up to 180. so I did this equation: (10x-20)+ (6x+8) = 180 and I solved for x
Answer:
length of CD = 18 units.
Step-by-step explanation:
In ΔABC and ΔCED,
AB║DE and AD is a transversal line,
m∠ABC = m∠CED [Alternate interior angles]
m∠ACB = m∠DCE [Vertically opposite angles]
ΔABC ~ ΔCED [By AA property of similarity]
Therefore, by the property of similar triangles, corresponding sides will be proportional.


CD = 6
Since, AD = AC + CD
AD = 12 + 6
= 18 units
Therefore, length of CD = 18 units.
Answer:
19
Explanation:
3x+4
Plug in 5 as x
3(5)+4
=15+4
=19
I hope this helps!
A. 4x - y = 8
y = -8 y-int (0,-8)
x = 2. x-imt (2,0)
b. 6x - y = -3
x = -1/2 (-1/2, 0) x int
y = 3 : (0,3) y-intercept
c. x = -5 x-int (-5,0)
y -int (0,25) y = 25
