Multiple the second equation by 2 and subtract it from the first
2x + 5y = 10
2x - 6y = -12
now subtract
11y = 22
y = 2
Plug y = 2 in to either equation
x - 3(2) = -6
x - 6 = -6
x = 0
The point at where they intersect is (0, 2)
Since bc = 6, that makes db = 3 and cd = 3rad3
cd (2) = ac. so ac = 6rad3
so to get ad, you square ac which = 108, square cd which = 3rad3 which equals 27. 108 - 27 = 81. the sqaure root of 81 is 9. ad = 9
Answer:
B. SUBTRACTION PROPERTY OF EQUALITY
Step-by-step explanation:
Answer:
x=6.09cm
Step-by-step explanation:
Working out AB:
7.5²+4.9²
= √80.26
AB= 8.96cm
To work out x:
AB is the opposite, where BC is the adjacent. This means that we have to use TOA.
x=8.96/Tan(55.8)
x= 6.09cm
