What is the correct classification for ∠QPS?
rewona [7]
∠QPS is part of the right angle, and it takes 90 - 21 degrees of it.
90 - 21 = 69°

Now take 69 and add 22, the rest of ∠QPS.
69 + 22 = 91

∠QPS is 91°, which is larger than a right angle, 90°, so that means it is an obtuse angle.

Serga [27]

Answer: The system of equation is,

2 ( x + y ) = 50

x = 2 y - 5

Step-by-step explanation:

Let x represents the length of the rectangular brownie and y represents the width of the rectangular brownie.

Thus, the perimeter of the brownie = 2 ( x + y )

But, According to the question,

Perimeter of the brownie = 50,

2 ( x + y ) = 50

The length of the brownie is 5 less than twice the width,

That is, x = 2 y - 5

Thus, the required system of equation is,

2 ( x + y ) = 50 , x = 2 y - 5
