We know that an equilateral triangle has all sides equal.
Initial perimeter = s + s + s = s
Each side has been increases by then the new perimeter is:
(s+15) + (s+15) + (s+15) = 3s + 45
So the new perimeter = 3s + 45
3x^3<span> + 17</span>x^2<span> + 21</span>x<span> - 9
this is the correct answer for this problem.</span>
I believe the answer is 1/216
Answer:
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
Step 2: Add 3x to both sides.
Step 3: Add 4 to both sides.
Step 4: Divide both sides by 7.
Answer:
Your answer would be 37°
Step-by-step explanation:
Since BC and DE are parallel, certain angles will be the same, such as the missing interior angle of the triangle and ∠DAF, which will also have the same measure as x.
We know that the sum of all of the interior angles of a triangle must equal 180°. So, we add 41 and 102 to get 143. This means that the missing interior angle must be 37°, since 37+143=180.
As mentioned above, because BC and DE are parallel, the missing interior angle has the same measure as ∠DAF, which is a vertical angle to x, and therefore also has the same measure. So, the measure of x is 37°.
Hope this helps you!
