Answer:
As the largest side is
15
yards and smaller sides are
9
yards and
12
yards
from Pythagoras theorem, if the triangle is right angled square of largest side should be equal to sum of the squares of smaller two sides.
Square of largest side is
15
2
=
225
and squares of smaller two sides are
9
2
=
81
and
12
2
=
144
.
As
225
=
81
+
144
, the triangle is right angled.

Answer: 12x+15y
Step-by-step explanation:
I think that x = 37/19
22x+54=−20+60x
Step 1: Simplify both sides of the equation.
22x+54=60x−20
Step 2: Subtract 60x from both sides.
22x+54−<u>60x</u>=60x−20−<u>60x</u>
−38x+54=−20
Step 3: Subtract 54 from both sides.
−38x+54−<u>54</u>=−20−<u>54</u>
−38x=−74
Step 4: Divide both sides by -38.
−38x/ <u>−38</u> = −74/<u>−38</u>
x=37/19
0.4w+5.6=0.2w+10
0.4w - 0.2w= 10- 5.6
0.2w =4.4
Divide both sides by 0.2
Which would get you : w=22
