Answer :-
The sides are:
A=135
B=95
C=130
L=100
W=20
And the perimeter is: 360
Further explanation:
Given that both figures have same parameter
Let P1 be the perimeter of the triangle and P2 be the perimeter of the rectangle
Then
P1=P2
Let the sides of triangle be
A = x+55
B= x+15
C = x+50
and
Sides of rectangle be
L = x+20
W = x
The sides are:
A=135
B=95
C=130
L=100
W=20
And the perimeter is: 360

Answer:
13.5
Step-by-step explanation:
Using sine rule
Tan25 = AC/AB = AC/29
AC = 29 × Tan 25 = 29 × 0.45 = 13.5229220865
Answer:
15. BE = 37.5
16. AD = 62.4.
17. ED = 37.5
18. Angle CDA=79 degrees
19. Angle BCD= 101.
20. Angle DAB=101.
Step-by-step explanation:
For problems 15-20, you'll use geometry theorem the definition of a parallelogram which says they have two pairs of equal parallel sides, equal opposite angles and that the diagonals in any parallelogram bisect each other into equal segments.
15. BE is half of 75. BE = 37.5
16. Since BC = 62.4 then AD = 62.4.
17. ED is half of 75. ED = 37.5
18. 79 degrees
19. Parallelograms add to 360 degrees so if two angles are 79 then 360-79-79 = 202 which is split equally in the other two angles. 202/2 =101. Angle BCD= 101.
20. Angle DAB is equal to Angle BCD so Angle DAB=101.
