Pythagorean Theorem can be used only for right triangles.
(leg1)² +(leg2)² = hypotenuse ²
So, answer is the right triangle B.
Hello!
Your answer is: 7
(X = "<em>A number</em>")
<em>"11 more than four times a number is 39"</em> in equation form is: 4X + 11 = 39
to solve, first subtract 11 from both sides:
4X = 28
then divide both sides by 4 to get:
X = 7
I hope this helps, and have a nice day!

Answer:
£289.20
Step-by-step explanation:
13:2 = x:16 or 13/2 = x/16
cross multiply: 208 = 2x
simplify: x = 104
16 blue tiles x £2.80 each = £44.80
104 white tiles x £2.35 each = £244.40
44.80 + 244.40 = £289.20
