Answer:
the correct answer is option A. Length
<h3>
<u>Given</u><u>:</u><u>-</u></h3>
- The hypotenuse of a right angle triangle is 13cm.
- One other side of the triangle is 1cm shorter than the hypotenuse.
<h3>
<u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u><u>-</u></h3>
Find the third scale of the triangle .
<h3>
<u>Solution:-</u><u> </u></h3>
Let the third Side be x.
According to the question,
★ Hypotenuse = 13 cm
★ Other side = Hypotenuse - 1 [ Given ]
= 13 cm - 1 cm
= 12 cm
Now,
<u>By pythagoras theorem</u>,
13² = 12² + x²
⇒ 169 = 144 + x²
⇒ x² = 169 - 144
⇒ x² = 25
⇒ x = √25
⇒ x = 5 cm
Hence, the third scale of the triangle is 5 cm.
Answer:
-2
Step-by-step explanation:
-7 + 5 = -2
If you have negatives and then add, the negative number will decrease.
if the question was -7 - 5, the answer would be -12. This is because when you subtract a number from a negative, the negative number becomes bigger.
320 students. Because you have to divide 384 by 6 which will give you 64 which is the number for the students that chose art and then subtract that from the total students which are 384 and you'll get 320 as your answer for the student that didn't pick art.
