To find AB(x) and BC(y), you can do(there are multiple ways you can do this):
tan A = 
tan 60° = or (tan 60°) · 7 = y
tan 60° = 
√3 · 7 = y
7√3 cm = y
sin B = 
sin 30° = or 
sin 30° = 
= 
x = 
x = 14 cm
AB = 14cm
BC = 7√3 cm
Repeating because its repeating 91.
Answer
10 ft sides
Step-by-step explanation:
Since its squared the easiest way to figure out the sides is to square root the area and square root of 100 is 10
Answer:
9
Step-by-step explanation:
sqrt(5) + sqrt(405)
sqrt(5) + sqrt( 81*5)
sqrt(5) + sqrt(81) sqrt(5)
sqrt(5) +9 sqrt(5)
10 sqrt(5)
The two numbers in each column have to add to 23
So under 7 you write 16, above 4 you write 19, etc
The rule will say x + y = 23
