Step-by-step explanation:
3+√5+3√5+5
=6√5+5
=6√10
54 is the hypotenuse because it is the longest side. Square all of the sides. So 54^2=2916
51^2=2601
22^2=484
Now you have 2916=2601+484
Add the two and they will be greater than 2916. Because of that, you will have an acute triangle because 22^2+51^2>54^2
In short, its B
Answer:
B or 7
Step-by-step explanation:
Start by doing what is in the brackets (10 + 25) = 35
Now worry about 35 / z
z = 5 Given
35 / 5 = 7
Answer: 7 which is B
Answer:
6/36 as simplified as 1/6
Step-by-step explanation:
Answer:
16.2
Step-by-step explanation:
Use the law of cos
c^2 = 8^2+10.4^2-2*8*10.4*cos(122.2 degrees)
=260.83
c = √260.83 = 16.15
