Answer: Karl runs faster than Linn by 0.77
Step-by-step explanation: Speed of Karl = 8.73
Speed of Linn = 9.50
∴ Karl runs faster by =9.50 - 8.73
=<u> 0.77</u>
Alright, lets get started.
Angle 3 and angle 4 are adjacent angles because they are having the common side.
They both are on straight line, so, their addition will be 180°.
Suppose angle 4 is x , hence
angle 4 + angle 3 = 180

Subtracting 89 from both sides

°
Hence angle 4 is 91°. : Answer
Hope it will help :)
ΔABC ≅ ΔDEF
I find it easier to see the congruencies if I write them underneath each other:
∠A ≅ ∠D
≅
∠B ≅ ∠E
≅
∠C ≅ ∠F
≅
I am pretty sure the answer is 1.
