For each triangle sum of it's angles must add to 180°.
We need to check if these angles satisfy that condition:
32°+51°+97°=180°
They do satisfy. Now we check if any angle has value that is not possible.
32° and 51° angles are OK.
97° angle is also OK. It is obtuse angle.
For each angle measures exactly one triangle exists. In this example we have an obtuse-angle triangle.
Answer:
d = 4
Step 1: Flip the equation.
Step 2: Add 7 to both sides.
Step 3: Divide both sides by 12.
A, c, d, f
hope this helps you :)
2x+3=17
subtract 3 from each side
2x+3 -3 = 17 -3
2x = 14
divide by 2 on each side
2x/2 = 14/2
x = 7
I believe it’ll be 4/10 = 12/20
