Answer:
A
Step-by-step explanation:
73+107 = 180. When the smaller of the two angles is 73 all of the smaller angles are also going to be 73 and since the angles MTS and STN are bigger angles they both have to be 107
Answer:
x - 6
Step-by-step explanation:
A = L x W
A / L = W
x^2-11x+30 / x -5 = W (Simplify the numerator)
(x - 6) x ( x - 5) / x - 5 = W (Cancel the similar ones which is (x - 5) )
x - 6 = W
Hope that helps
length = 1/2 w+9
perimeter= 60 =2(l+w)
substitute in for length
60 = 2(1/2 w +9 +w)
60 = 2 (3/2 w +9)
distribute
60 = 3w + 18
subtract 18 from each side
42 = 3w
divide by 3 on each side
14 = w
length = 1/2 w + 9
length = 1/2 (14) +9
7 + 9
16cm
When you lay them out then you know what you are dividing
