Answer:
B
Step-by-step explanation:
Answer:
x = -13
Step-by-step explanation:
Step 1: Write equation
-104 = 8x
Step 2: Divide both sides by 8
x = -13
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-104 = 8(-13)
-104 = -104
Answer:
45
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
3x+5x+4x = 180
Combine like terms
12x = 180
Divide by 12
12x/12 =180/12
x = 15
The smallest angle is 3x
3(15) = 45
