We know that
∠ECD=∠ACB------> given in the problem
∠DEC=∠CAB------> 90°
so
∠EDC=∠ABC
therefore
triangles EDC and ABC are similar
<span>So
the ratio of the legs are equal</span>
the answer isAC is equal to 126
Answer:
7 donkeys
Step-by-step explanation:
Given
A system consisting of donkeys and tourists
Heads = 50
Legs = 114
Required
Calculate number of donkeys.
Represent donkeys with D and tourists with T.
By means of identification; donkeys and tourists (human) both have 1 head.
This implies that
Number of Heads = D + T
50 = D + T ----- Equation 1
While each donkey have 4 legs, each tourists have 2 legs.
This implies that
Number of legs = 4D + 2T
114 = 4D + 2T ---- Multiply both sides by ½
114 * ½ = (4D + 2T) * ½
57 = 4D * ½ + 2T * ½
57 = 2D + T ----- Equation 2
Subtract equation 1 from 2
57 = 2D + T
- (50 = D + T)
---------------------
57 - 50 = 2D - D + T - T
7 = D
Recall that D represents the number of donkeys.
So, D = 7 implies that
The total number of donkeys are 7
Answer:
do m= 28.75 minus S
or do s= 28.75 minus m
Step-by-step explanation:
do m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus mdo m= 28.75 minus S
or do s= 28.75 minus m
Answer:
36
8 times 9 equals 72 and then you just divide that by two and it would be 36
