Answer:
25 in and 9 cm
Step-by-step explanation:
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the missing side
A
x² = 7² + 24² = 49 + 576 = 625 ( take square root of both sides )
x =
= 25
B
x² + 12² = 15²
x² + 144 = 225 ( subtract 144 from both sides )
x² = 81 ( take square root of both sides )
x =
= 9
Answer:
t=-6
Step-by-step explanation:
12/2=6
t-6=3t/2-3
t-3t/2=-3+6
2t/2-3t/2=3
-t/2=3
-t=3*2
-t=6
t=-6
