Answer:
z = 72°
Step-by-step explanation:
Complimentary angles sum to 90° , thus
z + y = 180, that is
z + 18 = 90 ( subtract 18 from both sides )
z = 72°
Answer:
The solution to the system of equations be:
Step-by-step explanation:
Given the system of equations
Let us solve the system by the elimination method
Arrange equation variables for elimination
subtracting the equations
so the system of equations becomes
solve 5x for x
Divide both sides by 5
Add 6 to both sides
Therefore, the solution to the system of equations be:
Answer:
8
Step-by-step explanation:
You can set up a proportion to find your missing side.
Let x be the missing side.
Cross multiply and solve for x.
144= 18x
8=x
