Friend the missing side of each triangle

√5
Because the triangle is a right triangle, we are able to use the Pythagorean Theorem to find the final side. Keep in mind that we have the hypotenuse and a leg, so we don't need to solve for the hypotenuse, c.

a² + b² = c²   Pythagorean Theorem
√10² + b² = √15²   Substitute
10 + b² = 15   Exponents
b² = 5   Subtract 10 from both sides
b = √5

The missing side is √5.

Hope this helps!

Right trianlge

a^2+b^2=c^2
wher a and b are legs and c=hypotnouse
(hypotonuse is side oposite right angle)

c=√15
one leg is √10, call it a
find x
(√10)^2+b^2=(√15)^2
10+x^2=15
minus 15 both sidees
x^2=5
sqrt both sides
x=√5

x=√5cm

Do the math. she originally had 50 dollars on her gift card and she had 12 dollars left on her gift card after she finished her shopping spree. if you subtract 50 minus 12 you get thirty eight dollars as your answer. so therefore, ciara spent 38 dollars total o
