In pythagoras's theorem, generally a is the shortest side, b is the second shortest and c is the hypotenuse:

. However, there is a problem. The questions aren't actually possible without using sine, cosine, and tangent (which are mathematical ratios if you didn't know). I can help you with this but it will take time explaining.
Answer:
9
get a common denominator between 6,12,7,2 = 84
Step-by-step explanation:

Answer:
5/6
Step-by-step explanation:
(2/3) / (4/5) = (2/3) * (5/4) Rock times roll, which means keep the first fraction the same ("rock"), change the division to "times", and "roll" the second fraction.
= (1/3) * (5/2) Simplify the 2 and the /4 since they are both even
= (1*5)/(2*3) Multiply the numerators together and the denominators together
= 5/6
True, for a contrapositive you switch the parts and then make them opposite, but the statement is still true.
Step-by-step explanation:

<u>Given</u><u> </u><u>:</u><u>-</u></h3>
- A triangle have two angles that measures 85° and 23°.
<h3>
<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u></h3>
- Measure of the third angle.
<h3>
<u>Solution</u><u> </u><u>:</u><u>-</u></h3>
Let the measure of the third angle of the triangle be x.
As we know that,
- The sum of all three sides of a triangle is 180° which is the angle sum property of triangle.
Therefore,





∴ Hence, the measure of the third angle of the triangle is 72°.
