Answer: Last Option
Step-by-step explanation:
By definition the sum of the internal angles of a triangle must always be equal to 180 °.
This means that:

Now we solve the equation for the variable x




We subtract 12 in both barks of the equation


Divide by 3 on both sides of the equation



Finally the measure of angle ABC is: (56-5)° = 51°
Answer:
The length of the rectangle is 30 feet.
Step-by-step explanation:
Because the equation for area is length times width, you would have to set the two equations to seventy and multiply them.
<em> (x+5) (x+2) = 70</em>
<em> </em><em>2x + 10 = 70</em>
Then, you would have to subtract ten from both sides, cancelling it from the left side.
<em> 2x = 60</em>
<em />
Then do the opposite and divide sixty by two, therefore getting a length of thirty feet.
