Answer:
The value of height of the building h = 509.2 feet
Step-by-step explanation:
From the Δ A B C
⇒ h = y 
° ------- (1)
From Δ A B D
⇒ h = ( y + 300 ) 
° ------- (2)
Equation 1 = Equation 2
⇒ y ° = ( y + 300 ) °
⇒ 0.46 y = 0.36 y + 109.2
⇒ 0.1 y = 109.2
⇒ y = 1092 feet
Put this value of y in equation ( 1 ) we get,
⇒ h = 1092 × tan 25°
⇒ h = 509.2 feet
This is the value of height of the building.
Answer:
10a: △ABC is an Equilateral triangle with all acute angles.
10b: △BCD is A scalene triangle with all acute angles.
10c: △BDE is An Isosceles triangle with one obtuse angle.
Step-by-step explanation:
10) Looking at the diagram at the bottom left;
- △ABC has 3 equal internal angles and as such, it means it will have 3 equal angles.
Thus, we can classify it as; Equilateral triangle with all acute angles.
- △BCD has 3 unequal angles. Thus, it's 3 sides are not equal. Also all the angles are less than 90°.
We can classify it as;
A scalene triangle with all acute angles
- △BDE has 2 equal angles and one angle greater than 90°. This means it has 2 equal sides.
Thus, we can classify it as;
- An Isosceles triangle with one obtuse angle.

Find the common difference.
Step-by-step explanation:
Answer:
6 teaspoon of salt
Step-by-step explanation:
All you need to do is find how many teaspoon of salt they have in total which in this case they have 1 and there are 3 1/3s in 1 teaspoon then you just have to do 3 times 2 and you get 6teaspoon of salt.
Hope this helps!
