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.

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

-4x+14+20x=2(10x-3)<br> not sure how to tackle this

katrin2010 [14]

That's a big one. Take it step by step.

-4x+14+20x= 2(10x-3)

Combine like terms.

16x+14= 20x-6

Add 6 on both sides.

16x+20=20x

Subtract 16x on both sides

20=4x

Divide by 4 into both sides.

x=5

Consider it tackled. Kaikers out.

I hope this helps!
