Answer:
a = 12cm
Third option
Step-by-step explanation:
Use the pythagorean theorem because this is a right triangle and you are looking for a missing side.
The formula is:
a² + b² = c², where "a" and "b" are sides, but "c" is the hypotenuse (longest side).
We know the hypotenuse and one other side.
Substitute side "b" and "c".
a² + 5² = 13²
a² + 25 = 169 Isolate "a"
a² = 169 - 25 Subtract 25 from both sides
a² = 144 Find the square root of both sides
a = √144
a = 12
The mssing side, "a", is 12 cm long.
15x+25y=1875
Let
y=95-x
15x+25 (95-x)=1875
Solve for x
15x+2375-25x=1875
15x-25x=1875-2375
-10x=-500
X=500/10
X=50 the number of $15 items
Y=95-50=45 the number of $25 items
Answer:
not adjacent: such as. a : not having a common endpoint or border non adjacent buildings/rooms. b of two angles : not having the vertex and one side in common.
