Answer:

ACB = 85

Step-by-step explanation:

First find x:

10+ x + 60 = 120 - x

x + 70 = 120 - x

Add x to both sides

2x + 70 = 120

subtract 70 from 120

2x = 50

Divide 2 from both sides

x = 25

10 + 25 + 60 = 95

Subtract 95 from 180

ACD = 85

Answer:

Step-by-step explanation:

1) 10+x+60=120-x

70+x=120-x

70+2x=120

-70

2x=50/2

X=25

2) acd= 120-25=95

A=10+25=35

B=60

C=180-95=85

Or 180-95=85

Answer is acb=85

Answer:

Side 1 = 8, side 2=6, side 3=3 1/3 or 10/3

Step-by-step explanation:

We can set up a proportion comparing the sides of the original triangle to the new triangle.

The original triangle has sides 12, 9, and 5. The new triangle has sides 8, e, and f (use whatever letters you like, it doesn't matter, but for me, e is the side with the middle length and f is the side with the shortest length.

We can write 3 ratios, with the length of the new triangle over the length of the old triangle.

8/12 e/9 f/5

To figure out e and f, put each ratio equal to 8/12.

8 = e Then multiply both sides of the equation by 9 and get 72 = e, 6=e.

12 9 12

8 = f Then multiply both sides of the equation by 9 and get 40 = f, 10=f.

12 5 12 3

10/3 can be rewritten as 3 1/3.
