You'll have to work out the length of the third side using:
a) the sine rule (if information given has one side opposite a given angle and the unknown side also opposite a given angle)
SIN RULE: sinA/a = sinB/b = sinC/c
b) the cos rule (not opposite).
COSINE RULE: a2 = b2 +c2 -2bc x CosA

What is the perimeter of a triangle whose sides measure 10 cm 15 cm and 18 cm?
Perimeter of a triangle is given by: sum of the three sides =(10+15+18)cm =43cm Done.
What is the perimeter of an equilateral triangle whose sides measures 8.5 meters?
An Equilateral Triangle has 3 equal sides so 3 X 8.5m = 25.5m
How to find the perimeter of an eQuilateral triangle whose sides measure 5 cm?
The figure is a triangle. That means it has 3 sides. The triangle is "equilateral". That means all three sides have the same length. One side is 5 cm. That means each of the other 2 sides is also 5 cm. So the perimeter is (5 + 5 + 5) = 15 cm.
What is the irregular shape with the perimeter of 36cm?
It could be any irregular shape whose sides add up to 36cm as for example a scalene triangle
What is the perimeter of an equailateral triangle whose side measure 7.5 cm?
It is: 3*7.5 = 22.5 cm which is the perimeter of the equilateral triangle
Is the perimeter of the triangle whose sides measure 7.5 7.1 and 8.1?
is the perimeter of the triangle whose sides measure 7.5 7.1 and 8.1
What is the perimeter of a triangle whose sides measure 10 cm 15 cm and 18 cm?
Perimeter of a triangle is given by: sum of the three sides =(10+15+18)cm =43cm Done.
How do you find perimeter of triangle whose two sides are given and also angles are not given?
One can't. The angle between those is needed.
What is the perimeter of a triangle whose sides are 4cm 6cm and 12cm?
22cm
What is the perimeter of an equilteral triangle whose sides measure 9.5m?

What is the perimter of an equilateral triangle whose sides measure 7.5 centimeters?
The perimeter is 22.5 centimeters.
What is the perimeter of an equilateral triangle whose sides measures 8.5 meters?
An Equilateral Triangle has 3 equal sides so 3 X 8.5m = 25.5m
What is the perimeter of a triangle whose sides measure 15 cm 17 cm and 10 cm?
42cm
What is the perimeter of a triangle whose sides measure 6 8 and 10 inches?
6+8+10=24The perimeter of the triangle is 24 inchesThe perimeter is all the side lengths added up, so that triangle would have a perimeter of 24 inches.6+8+10=24 inches
