Answer:
8 1/5 + 9 1/2 = 177/10 = 177/10 = 17.7
Step-by-step explanation:
So first you make two isosceles triangles, one is URS and the other is UST. First find the degrees of angle RSU which is (180-120)/2=30. Then you know that TSU is 70 and then you can find angle T is 180-70*2 which is 40.
Another method, which is faster is that in a quadrilateral, all angles make 180 degrees. 120+100+100 is 320 and 360-320 is 40.
Answer:
420 = T
Step-by-step explanation:
500 is 80 more than T
so reverse the problem to make it
500 - 80
and that equals 420
making the answer 420=T

The number of robberies in Springfield in 2013 is 250.</h3>
Step-by-step explanation:
Here let us assume that the number of robberies in 2013 = m
Given the number of robberies in 2014 = 315
As we can see the robberies has risen by 26% .\
⇒ 26% + 100 % of Robberies in 2013 = 315
⇒ 126% of m = 315
or, m = 250
Hence, the number of robberies in Springfield in 2013 is 250.
