Step-by-step explanation:
perimeter=28
length=2x
width=x
28=2(x+2x)
28=2x+4x
28=6x
28/6=6x/6
4.67=x
width=4.67
length=2×4.67
=9.34
Answer:
D
Step-by-step explanation:
Triangle, rectangles, pollygon, robtuse, i hope this is what you mean
The answer is 142°
Explanation:
angle 1 and angle 2 form are supplementary.
m∠1 + m∠2 = 180°
38° + m∠2 = 180°
m∠2 = 180° - 38°
m∠2 = 142°
Hope it helps!
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.
