Answer:
x = 24 , y = 19
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
2x - 8 = x + 16 ( subtract x from both sides )
x - 8 = 16 ( add 8 to both sides )
x = 24
and
2y = y + 19 ( subtract y from both sides )
y = 19

Answer:
(i) The equivalent coordinates in rectangular form are
.
(ii) The equivalent coordinates in rectangular form are
.
Step-by-step explanation:
In this exercise we must find the equivalent coordinates in rectangular form from polar form. That is:

Where:
- Norm of vector, dimensionless.
- Direction of vector with respect to +x semiaxis, measured in sexagesimal degrees.
(i) (
,
)


The equivalent coordinates in rectangular form are
.
(ii) (
,
)


The equivalent coordinates in rectangular form are
.
Answer:
x = 110°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6, thus
sum = 180° × 4 = 720°
Sum the given angles and equate to 720
125 + x + 130 + 90 + 165 + 100 = 720, that is
610 + x = 720 ( subtract 610 from both sides )
x = 110°
