Answer:
Only option C: The shortest side can equal 7 cm.
Step-by-step explanation:
Let the length of the shortest side be x cm, then the length of the longest side is 4x cm. Let the length of the middle side be y cm. Note that
The perimeter is
A. The value x cannot be 40 cm, because then y is negative
B. If the longest side is 30 cm long, then
But
This means that such triangle does not exist
C. If x=7 cm, then 4x=28 cm,
Since,
such triangle exists and this option is possible
D. If x=25 cm, then y is negative
E. If x=5 cm, then 4x=20 cm and
But this triangle does not exist, because
Answer:
x ~0.9
Step-by-step explanation:
To solve for (x) in the given right triangle, use the trigonometric ratios, which are the following,
Each of the sides of a triangle is named with respect to the given angle. In this problem, one is given the side opposite to the given angle, and the side adjacent to it. Use the ratio of tangent (tan) to solve for the unknown side.
Manipulate the equation so that it is solved for (x),
x ~ 0.859
