Answer:
4
Step-by-step explanation:
Both triangles are the same shape, just to different scales. In order to find out the length of side AB in triangle ABC, you have to find out the length of side PQ in triangle PQR and how much bigger than side AB is.
You can tell that sides AC and PR are similar, and 30/5 is 6. You see also that sides BC and QR are similar, and 42/7 is also 6. We have now discovered that triangle PQR is 6 times bigger than triangle ABC.
So now, to find the length of the missing side, we have to shrink side PQ by 6. 24/6 is 4. Therefore, the length of side AB is 4.
Answer:
Step 1: Define your variables. You should begin with a specific research question. ...
Step 2: Write your hypothesis. ...
Step 3: Design your experimental treatments. ...
Step 4: Assign your subjects to treatment groups. ...
Step 5: Measure your dependent variable.
Step-by-step explanation:
Generally, the experimental unit is the person, animal, or object that is the subject of the experiment. Experimental units receive different treatments from one another in an experiment.
We know that the sum of the interior angles of a triangle must equal to 180°.
So to find the missing angle on the inside of triangle FGH, we must subtract 53° and 45° from 180°:
So we know that the missing interior angle is 82°. We also know that a straight line has an angle of 180°.
x° + the interior angle that we just found must then equal to 180°, since ray HG is a straight line.
So we need to subtract 82° from 180° to find x°:
So now we know that
x° is equal to 98°.
Answer:
<h2><u><em>
m = 1/5</em></u></h2>
Step-by-step explanation:
4m = 6m - 2/5
-2m + 2/5 = 0
m = (-2/5)/-2
m = 1/5
---------------
check
4 * 1/5 = 6 * 1/5 - 2/5
4/5 = 6/5 - 2/5
<em>4/5 = 4/5</em>
<u>the answer is good</u>
