the length of a leg on a 45-45-90 triangle given the hypotenuse is half the length of the hypotenuse times sqrt(2)
hypotenuse = 10
10/2 =5
so the answer should be 5sqrt(2), which I don't see as a choice

Answer:

Step-by-step explanation:
First, find the area of the bigger shape. Then, separately, find the smaller shape's area. Subtract the smaller one by the big boi, and you'll get the area of the shaded area. You can count the little squares too.
12*8=96
4*6=24
96-24=72
No.
Answer:
5 - 2 x 9 + 9^2 divided by 3

Answer:
d. 50°
Step-by-step explanation:
Since you know one angle and its opposite side, use the law of sines.
sin 36°/11.9 = sin D/15.6
sin D = 15.6 × sin 36° / 11.9
sin D = =0.7705
D = sin^-1 0.7705
D = 50.4°
