<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:
Step-by-step explanation:
Here, we want to solve the given quadratic equation using the quadratic formula
We need to rewrite the equation in the standard form;
-4x^2 + 3x + 5 = 0
we have the value a as -4
value b as 3
C = 5
we then substitute these values into the quadratic formula as seen in the attachment
X= -2x -15y -45 maybe i’m kinda stupid
