<h2>Answer:</h2>

<h2>Explanation:</h2>
Given the equation expressed as:

First, we need to calculate the value of "x" from the given expression.
Step 1: Given the equation 2x + 5 = 8x
Step 2: Subtract 5 from both sides:

Step 3: Subtract 8x from both sides

Step 4: Divide both sides by -6

Step 5: Get the value of 12x. Substitute x = 5/6 into the expression to have:

Therefore the value of 12x is 10
Factor 28 and 49
28
1*14
1*2*7
49
7*7
7 is the answer
Answer:
∠3 is 70°
Step-by-step explanation:
∠1 is 50° since it is across from another 50° angle
and then you use the equation x+25+2x+50=180 to find x
x then equals 35°
you then use the alternate interior angle theorem to say that ∠3 is 2x, or 70°
