Answer:
<h2>x = - 3</h2>
Step-by-step explanation:
<u>Multiply the terms in the bracket</u>
That's
Subtract 2x from both sides of the <u>equation</u>
<u>Divide both sides by 4</u>
We have the final answer as
<h3>x = - 3</h3>
Hope this helps you
If Nick starts with 20, we can just plug it into p/2 - 12 to get 10-12 or -2. This means Nick did not get 20 cards. Now we have answered both. Two-liner!
X=26
Because 90-38=52
52/2=26
The height of the building is 3 feet
<h3>How to determine the value</h3>
From the information given, we have that;
- Angle of elevation = 4. 72 degrees
- hypotenuse side = 36 feet tall
- Building height is the opposite side
Using the sine identity:
sin θ = opposite/hypotenuse
Substitute the values
sin 4. 72 = x/ 36
cross multiply
x = sin 4. 72 × 36
x = 0. 0822 × 36
x = 3 feet
Thus, the height of the building is 3 feet
