Answer:
The length of AB = 97/3 units
Step-by-step explanation:
We know that a rhombus is a quadrilateral whose four sides all have the same length.
Thus, the equation becomes
7x+2 = 4x+15
7x-4x = 15-2
3x = 13
x = 13/3
So, the length of CD = 7x+2 = 7(13/3)+2
= 91/3 + 2
= 97/3
And, the length of BC = 4x+15 = 4(13/3) + 15
= 97/3
- We already know that a rhombus is a quadrilateral whose four sides all have the same length.
Thus, the length of AB = 97/3 units
Answer:
84.5
Step-by-step explanation:
12.3(3)+11.9(4)=84.5
Answer:
(x, y) = (18, 5)
Step-by-step explanation:
Assuming the three lines meet at a single point at lower left (the figure is sloppily drawn), the angle (3x)°+49° is a corresponding angle to (7x-23)°. That means they have the same measure:
3x +49 = 7x -23
72 = 4x . . . . . . . . . add 23-3x
18 = x . . . . . . . . . . . divide by 4
__
Angles (3x)° and (11y-1)° are "corresponding" angles, so are congruent.
3x = 11y -1
3(18) +1 = 11y . . . . add 1, fill in the value of x
55/11 = y = 5 . . . . divide by 11
The values of x and y are 18 and 5, respectively.
We have that
1) the lateral area----------------> L=P*h
P=(3+3+3) h=6
L=(3+3+3)*6=54 in²
the answer part 1) is the lateral area is 54 in²
2) the total area=------------- > S=P*h+2B
2B=2*[3*3/2] P*h=54
S=2*[3*3/2]+54=63 in²
the answer part 2) is the total area is 63 in²
Answer:
55
Step-by-step explanation:
33/60 = 0.55 * 100 = 55
Check:
55*0.6 = 33
Hope that helps!
