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.
Answer:
x = 33
<C = 81
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+ 2x+ 2x+15 = 180
Combine like terms
5x+15 = 180
Subtract 15 from each side
5x +15-15 =180-15
5x = 165
Divide by 5
5x/5 =165/5
x = 33
<C = 2x+15 = 2(33)+15 = 66+15 = 81
