Answer:D 120 degrees, F 60 degrees
Step-by-step explanation:
it is a parallelogram which means the 2 angles add up to 180 degrees. 5x+2x+12=180. Then solve, 7x=168, x=24. Then Substitute back into the angles. E is 5*24 which is 120. F is same as D which is 2x+12=60. Hope this helped

Answer:
19.55%
Step-by-step explanation:
%change = (895-720)/895 * 100
= 19.55%
Since the original is more than the later, then it is a decrease
Answer:
CN Tower = 550 m and church tower = 160 m
Step-by-step explanation:
The first equation x + y = 710 is correct
but the second one is
x - y = 390
Note x = height of the CN tower and y = height of the church.
x + y = 710
x - y = 390
If we add the 2 above equations we eliminate y so
2x = 1100
x = 550 m
and y = 710 - 550 = 160 m
Answer:
a)2/7
b)41/48
<em />
<em>Step-by-step explanation:</em>
<u>-Question A-</u>
1) Rephrase the problem to look like this:
3/7*28/15*5/14 <-- when dividing fractions you actually multiply by the reciprocal (opposite)
2) Multiply across the above phrase:
420/1470
3) Simplify your fraction:
2/7
There is nothing else to be done with 2/7 and thus it is your final answer.
<u></u>
<u>-Question B-</u>
1) Get the denominator of all 3 fractions to the same Least Common Denominator (48):
42/48 + 3/48 - 4/48
2) Do the arithmetic in the phrase above:
41/48
41/48 cannot be simplified and thus is your final answer
