Given:
Point F,G,H are midpoints of the sides of the triangle CDE.
To find:
The perimeter of the triangle CDE.
Solution:
According to the triangle mid-segment theorem, the length of the mid-segment of a triangle is always half of the base of the triangle.
FG is mid-segment and DE is base. So, by using triangle mid-segment theorem, we get
GH is mid-segment and CE is base. So, by using triangle mid-segment theorem, we get
Now, the perimeter of the triangle CDE is:
Therefore, the perimeter of the triangle CDE is 56 units.
Answer:
Picture 1 x = 43°
Step-by-step explanation:
Picture 1 - When a triangle is formed inside a semicircle, two lines from either side of the diameter meet at a point on the circumference at a right angle.
180 - 47-90= 43° = x
Answer:
L = w+2
L+w = 60
W+2+w = 60
2w+2 = 60
W+1 = 30
W = 29
L = 31
Answer:
5) C pink 6) A -1/2x + 1/4 7) D z ≥ 0
Step-by-step explanation:
5) White 1/6 = 4/24
Green 1/3 = 8/24
Pink 1/8 = 3/24
Yellow 3/8 = 9/24
6) 11/2x - 2(3x - 1/8) Distribute the -2
11/2x - 6x + 1/4 Combine like terms
-1/2x + 1/4
7) z ≥ 0
z is greater than or equal to 0
