The answer is going to be 5
Answer:
B= 4.6cm
Step-by-step explanation:
A= ![\frac{H_{b} B}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BH_%7Bb%7D%20B%7D%7B2%7D)
![B= 2\frac{A}{H_{b} } = 2 * \frac{17.25}{7.5}](https://tex.z-dn.net/?f=B%3D%202%5Cfrac%7BA%7D%7BH_%7Bb%7D%20%7D%20%3D%202%20%2A%20%5Cfrac%7B17.25%7D%7B7.5%7D)

Is that correct?
First, we determine the area of the wall before cutting out the door by multiplying the dimensions given.
area of wall = ( 9 ft)(5.25 ft) = 47.25 ft²
Then, we determine the area of the door by subtracting from the total area the area of the remaining wall.
area of door = 47.25 ft² - 26.25 ft² = 21 ft²
The two whole numbers that can be the sides of the door are 7 ft x 3 ft.
Answer:
125°
Step-by-step explanation:
A triangle is 180°. You already have 2 angle measures given.
30° + 25° = 55° 180° - 55° = 125°
Angle y is an obtuse angle, an angle measure greater than 90°.
