The height of the shed is 2.325 m
The complete question is
The roof of a lean-to-garden shed has a gradient of 0.35.find the height....they have given the base as 1.5m and a shorter height 1.8m its like a house
<h3>What is a right Triangle ?</h3>
In a Triangle when one angle is 90 degree , the triangle is called Right Triangle .
Structure of the house is a right triangle with base = 1.5m
(height of that triangle)/1.5 = 35/100
height of that triangle = 1.5*0.35 = 0.5250
Ans: greater height of the lean-to = 1.8 + 0.5250 = 2.325 meters.
The height of the shed is 2.325 m.

Answer:
C. 18 cm
Step-by-step explanation:
The ratio of the sides of the triangle shown is 12 : 15 = 4 : 5. We know it is a right triangle, so we know the missing side length completes the ratio
3 : 4 : 5 = 9 : 12 : 15
Half of XY is 9 cm, so the length of the entire chord is 18 cm.
_____
The chord is tangent to the inner circle, so makes a 90° angle with the radius to that tangent point. This tells you that the triangle shown is a right triangle. It also tells you that the short radius bisects the chord. The Pythagorean theorem can be used to find the length of the side not shown (half the chord length).
The unknown side (a) can be found from ...
15² = 12² +a²
225 -144 = a² . . . . . . subtract 12²
81 = a² . . . . . . . . . . . simplify
9 = a . . . . . . . . . . . . . take the square root
The chord length is 2a, so is ...
2(9 cm) = 18 cm . . . . length of chord XY
14 because they are vertical angles
