Answer:
The answer is 2.
This is because on the left side of the triangle, we can see that the original length is ten cm greater than the second variation. therefore, the other side would also be 10 cm greater than the other variation's side. 5(2)×10= 20, which keeps the triangle to scale.

Answer:
∅ = 42°
Step-by-step explanation:
90 - 48 = 42° because 48 and 42 are complimentary angles (add up to 90°)
because the radii lines form an isosceles triangle, ∠∅ also = 42°
Answer:
115
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 7 - 1 = 13 - 7 = 19 - 13 = 25 - 19 = 6
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = 6 , thus
a₂₀ = 1 + (19 × 6) = 1 + 114 = 115
The discount is $165, and the final cost is $385.

Solve the first part of the equation
2.5 X 10 = 25
2.5 X - x = - 2.5x
+ 21
which all added together equals - 2.5x + 46
Now for the second part of the equation
- 3.5 X 3x = - 10.5x
- 3.5 X 20 = - 70
+ 84
which all added together gets you - 10.5x + 14
once you have both parts of the two sides solved, you have to start subtracting from each sides
- 2.5x + 46 = -10.5x + 14
- 46 + 46
- 2.5x = -10.5x + 60
-10.5x +10.5x
-13x = 60
60 ÷ -13x
x = -4.61
