Answer:
Length of the mural should be 20.78 m
Step-by-step explanation:
Let the length of the mural be L and the width W
Area = L × W = 60 m²
Ticket wants the L = 15 + 2W
Substitute for L in the Area eqn
(15 + 2W) × W = 60
15W + 2W² = 60
2W² + 15W - 60 = 0
Solving the quadratic equation
W = 2.89 m or - 10.39 m
Obviously, the width cannot be negative,
So, W = 2.89 m
L = 15 + 2W = 15 + 2(2.89) = 20.78 m
Check - L × W = 20.78 × 2.89 = 60 m²
Hope this Helps!!!

Answer:
130
Step-by-step explanation:
? is an exterior angle of a triangle
An exterior angle is equal to the sum of the two opposite interior angles ( 35 and 95 in this case )
That being said the missing angle = 95 + 35
95 + 35 = 130
Hence, the answer is 130
