Answer:
split the other three in half
Step-by-step explanation:
Okay. An obtuse triangle is any triangle that has 1 angle that measures more than 90°. As we can see, angle QRS measures 76° and angle PRQ measures 104°. 104 > 90. Triangle PQR is a closed figure, and a triangle measures 180° total. There can only be 1 obtuse angle in any triangle. PRQ is an obtuse angle. Therefore, triangle PQR is an obtuse triangle.
The answer is C
10% = 0.10
12 x 0.10 = 1.20
12 - 1.20 = 10.80
