Answer:
The length of the diagonal is closest to 51 cm.
Step-by-step explanation:
Given:
TV screen is 41 cm long and 31 cm high.
Now, to find the length of the diagonal.
By using pythagorean theorem:
leg 1 = 41 cm, leg 2 = 31 cm.
Let the hypotenuse be
.
(leg 1)² + (leg 2)² = hypotenuse²

⇒
⇒
<em>Using square root on both sides we get:</em>
⇒
<u><em>So, the length of the diagonal = 51.40 cm. </em></u>
<u><em>By rounding off of 51.40cm it becomes 51 cm.</em></u>
Therefore, the length of the diagonal is closest to 51 cm.
0.75x-18.5-0.65x=0
0.1x-18.5=0
0.1x=18.5 divide each term by 0.1
x=185
Answer:
9.425
Step-by-step explanation:
first find the total length of a circle with the radius being 2cm
which u will obtain 12.566
not forget that in circle 90 degrees =1/4
so u will find 1/4 of 12.566 which= 3.141
then subtract 3.141 from 12.566
=9.425
