I saw the image. QRST is a rectangle.
It has 4 right angles or 90° angles. ∠QRS ∠RST ∠STQ ∠TQR
Based on the image: ∠TQS and ∠RQS are complementary angles. This means that the sum of their angles is 90°
∠TQS is 24°. Thus, ∠RQS is 66°
90° - 24° = 66°
∠TQS + ∠RQS = 90°

Step-by-step explanation:
She can mow 25 lawns.
This is because 40/8 = 5, so multiply 5x5 and you get 25z

Step-by-step explanation:
Answer:
hotdog $1, and hamburger $2
Step-by-step explanation:
D-is hot dogs, H-hamburgers
7D +4H = 15
4D +7H = 18
we got 2 equations with 2 unknown so we can solve
7D +4H = 15 multiply by 7
4D +7H = 18 multiply by -4
49D +28H = 105
-16D -28H = -72 add the two equations
33D= 33 so D=$1
go back to the first equation:
7*1 +4H =15 gives us 4H = 15-7; 4H = 8 so H= $2
