6y-x
you have to plug in the numbers for x and y so it would be (6x4)-6 then you you solve this you do whats in parentheses first. Your problem should look like this 24-6 then you subtract that and you get 18. 18 will be your final answer.
Answer:
According to AD=BC So AC=BD
Step-by-step explanation:
AD = BC and angle ADC = angle BCD
we have to prove AC = BD
let's see ∆ADC and ∆BCD
AD = BC [ given ]
angle ADC = angle BCD [ given ]
CD = CD
from S - A - S
∆ADC congruence ∆BCD
Answer:
x = 15
Step-by-step explanation:
Interior angles and their exterior angles make a supplementary angle meaning they have a sum of 180°. Knowing this, we can make an equation to solve for x.
x + 165 = 180
x = 15
The answer is 6 kilometres
