You have two crossed lines. They form a total of 4 angles. The x and 78 are straight across from each other. When that happens, the two angles are labeled as vertically opposite angles.
Vertically opposite angles are always equal
x = 78 <<<<<<<< answer
Y=2x-4
X+2y=10
Put y into the x equation
X+2(2x-4) =10
Expand and simplify
X+4x-8=10
5x-8 =10
5x=10+8
5x=18
X=18/5
Insert x into the original equation to get y
Y=2x-4
Y=2(18/5)-4
Y=16/5
Answer:
The third one is correct
Step-by-step explanation:
Answer:
TRUE
Step-by-step explanation:
y-4 = 2(x-1)
here, 4 is representing the y value and 1 is representing the x value.
And the slope is 2.
I plugged it in to a truncated square pyramid calculator and got v=76
the formula for this shape is V=1/3(A squared+AB+B squared)H.
