Answer: 19.8 Units
Step-by-step explanation:
The triangle is shown in the attached figure, and have three vertices: 
, 
and 
.
Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.
In this sense, the modulus 
is calculated as shown:
Hence, for each vector:
Now, the perimeter of a triangle is the sum of its three sides:
Finally:
It would be a reflection across the x acess
Answer:
x = 60
Step-by-step explanation:
the chord- chord angle x is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
The sum of the arcs in a circle = 360° , then
intercepted arc = 360° - (35 + 25 + 205)° = 360° - 265° = 95°
then
x = 
(95 + 25 ) = × 120 = 60
