Find the unknown side of the triangle when x =
12 in and y = 5 in.
2 answers:
Answer:
13
Step-by-step explanation:
As x and y are perpendicular - we can use pythagoras.
So, The length of side x squared + The length of side y squared = The missing length squared.
12^2=144
5^2=25
144+25=169
sqrt169=13
Answer:
Unknown side = 13 in
Step-by-step explanation:
If it is a right sided triangle, then you can use the Pythagoras theoreum.
unknown side = u
x² + y² = u²
12² + 5² = u²
u² = 144 + 25
u² = 169
u = + - SQRT(169)
{Only the positive value has a meaning}.
Unknown side = 13 in

Answer:
187 t-shirts and 374 hoodies.
Step-by-step explanation:
(t is shirts)
561 = t + (2t)
561 = 3t
/3. /3
187 = t
ck:
187 + ( 2 times 187) = 561
187 + 374 = 561
561 = 561
