Answer:
the maximum value is 7
The minimum value is 0
Step-by-step explanation:
Step One : Interpret the question
The above question can be written like
The Equation
The diagram of the triangular plate and the bounded lines is shown on the first uploaded image
From the diagram 


Partial differentiation of the equation w.r.x

Partial differentiation of the equation w.r.y
Looking at the diagram the maximum value is 7 i.e at (x , y) = (0,1)
The minimum value is 0 i.e (x , y) = (0,0)
Answer and Explanation:
Because of the fact that the sum of the three interior angles of a triangle must be 180 degrees, a triangle could not have two right angles.
Alright, so you can try to study hard and gain a passing grade (A+) for the other two quarters.
Answer:
∠7 = 81°
Step-by-step explanation:
∠1 = ∠7
3x + 18 = 2x + 39
3x - 2x = 39 - 18
x = 21
∠7 = 2x + 39
∠7 = 2(21) + 39
∠7 = 42 + 39
∠7 = 81°
