Answer:
None of the above option is correct
The perimeter of the Pentagon is 21x + 19
Yes, since 2 *4 = 8, and then add the x- value at the end.
Answer:
Step-by-step explanation:
<u><em>The question is </em></u>
Find the value of x
we know that
If sin(A)=cos(B)
then
angle A and angle B are complementary angles
so
In this problem
so
solve for
Answer:
x = 5
Step-by-step explanation:
When two straight lines intersect, four angles are formed. The angles that are directly opposite of each other are equal. Since the angles are equal set the values equal to each other and solve for x.
5x - 5 = 2x + 10
5x - 5 - 2x = 2x + 10 - 2x
3x - 5 = 10
3x - 5 + 5 = 10 + 5
3x = 15
3x/3 = 15/3
x = 5
