512 there good luck hope u do good if u have any questions let me know
Answer:
280 cm2
Step-by-step explanation:
1)find the area of square
A=LW
=10×10
=100
2) find the area of triangle
A=B×H÷2
=10×9/2
=45
Coz,there are 4 triangle we multiple by 4
=45×4
=180
3)find the total surface area by adding the two
=100+180
=280cm2
Answer:B
Step-by-step explanation:
Call this triangle ABC, with A at the top vertex, B at the right angle, and C at the last vertex.
Tan (A)= 6/10 = 3/5
B is not acute
Tan (C)= 8/6= 4/3
Tan^-1 ( 3/5) =30.96375653...
Tan ^ -1 ( 4/3) =53.13010235...
Thus, tan(B) is the smallest.
Looking at the answer choices, it is B.
