Answer:
65/5
Step-by-step explanation:
You just need to multiply 13 by 5.
Answer:
P = 1.5x.
Step-by-step explanation:
Let the length of each side of the first triangle be x, then
Perimeter of this triangle
= 2x + 1.5x
= 3.5x.
So perimeter of smaller triangle is:
P = 1/2 * 3.5x
P = 1,.5x.
The other angle measures 112°.
All the angles in any 4-sided polygon will add up to 360°, like how all angles in a triangle add up to 180°. A good way to remember this is with the sum of interior angles formula:
180 x (n - 2), where n is the number of sides.

Common difference = 2nd term - first term
= -13-(-6)
= -13+6
= -7
