a is SSS, c is SAS and d is ASA, all good congruent triangle theorems.
b is AAA, good to show similar triangles, not necessarily congruent triangles.
Answer: b
Answer=3.08
5 7
____=____
2.20 x
cross multiply
5x=15.4
divide both sides by 5
x=3.08
The length of the shortest ladder that will reach from the ground over the fence to the wall of the building is 7.6 feet
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Pythagoras theorem is used to show the relationship between the sides of a right angled triangle. Hence:
Let l represent the length of the shortest ladder that will reach from the ground over the fence to the wall of the building.
l² = 3² + 7²
l = 7.6 feet
The length of the shortest ladder that will reach from the ground over the fence to the wall of the building is 7.6 feet
