Answer:

One possible side length could be a length of 6.7.

Step-by-step explanation:

We can assume that the hypotenuse of the triangle is 9 and one side length is 6. We can find the third side length using the pythagorean theorem [ a² + b² = c² ]. Use what we are given and solve for b.

6² + b² = 9²

36 + b² = 81

b² = 45

b ≈ 6.7

Best of Luck!

In a triangle, one angle is 3 times the first, another is 5 times the first. How large is the largest angle in degrees? round yo
Leno4ka [110]

let's recall that a triangle has a total of 180° for its interior angles.

x = first angle

3x = second angle, three times the first one

5x = third angle, five times the first one, and largest.

\bf x+3x+5x=180\implies 9x=180\implies x = \cfrac{180}{9}\implies x = 20 \\\\\\ \stackrel{largest}{5(x)}\implies 5(20)\implies 100
