Let’s say
Length= L
Width= W
L=2w
L+L+w+w=48 = 3L=48
48/3=16
L=16
W=8
see the attached figure to better understand the problem
we know that
In a parallelogram opposite angles are congruent, and consecutive angles are supplementary
So
in this problem
∠Y=
°
∠W=∠Y
∠W=
°
∠Z=∠X
∠Y+∠Z=
°
∠Z=
∠Z=
°
∠X=∠Z
∠X=
°
therefore
the answer is
∠Y=
°
∠W=
°
∠X=
°
∠Z=
°
Answer:
5 :12 ; what is the ratio of the number of gumamela to the total number of flowers
5 : 7 ; what is the ratio of the number of gumamela to the number of orchids
7:5 ; what is the ratio of the number of orchids to the number of gumamela
12 : 5 ; what is the ratio of the total number of flowers to the number of gumamela
12 : 7 ; what is the ratio of the total number of flowers to the number of orchid
Step-by-step explanation:
Ratios of a to b ;is written as a : b
Ratio of b to a is written as b : a
The ratio of a to the sum of a and b equals ;
a : (a + b)
Number of orchids = 7
Number of gumamela = 5
Total number of flowers = 7 + 5 = 12
Answer:
14
Step-by-step explanation:
7h-5(3h-8)=-72
or, 7h-15h+40=-72
or, 40+72=15h-7h
or, 112=8h
or, h=112/8
therefore,h=14
