Answer:
The envelop is 15.49 inches tall
Step-by-step explanation:
To find how tall the envelop is, we will follow the steps below;
We can use Pythagoras theorem formula to find the height of the envelop'
adjacent =width of the envelop= 11 inches opposite= height (h) of the evelope = h and hypotenuse = diagonal of the envelop= 19 inches
Using Pythagoras theorem;
opposite² + adjacent² = hypotenuse²
h² + 11² = 19²
h² + 121 = 361
subtract 121 from both-side of the equation
h² + 121-121 = 361-121
h² = 240
Take the square root of both-side
√h² =√ 240
h≈15.49 inches
The envelop is 15.49 inches tall
