It is 54. Draw it out. You will see that DCB - RCB = DCR
You have to expand the expression so that it becomes
3m+3n
We apply the Pythagorean theorem twice and obtain:
12 ^ 2 = x ^ 2 + (15-d) ^ 2
9 ^ 2 = x ^ 2 + d ^ 2
We observe that it is a system of two equations with two unknowns whose solutions are:
(x, d) = (-36/5, 27/5)
(x, d) = (36/5, 27/5)
We ignore the negative solution, therefore, the solution is:
(x, d) = (36/5, 27/5)
Answer:
The length of the new fence is:
x = 36/5 meters
Answer:
x=5
Step-by-step explanation:
The angles of a trangle have to add up to 180 degrees. With that information, we can create an equation:
27+98+(10x+5)=180
125+10x+5=180
130+10x=180
-130 -130
______________
10x=50
/10 /10
x=5
