Answer:
No because 16+49 does not equal 121.
Step-by-step explanation:
first make 11 the hypotenuse and 4 and 7 side b and A
Use the pythagorean theorem: A^2+B^2=C^2
4^2+7^2=11^2
16+49=121
Answer:
x=5
Step-by-step explanation:
The right angle opposite is the hypotenuse
The 30° is the opposite
SohCahToa
Soh = Sin because you got Opposite and Hypotenuse (because you're trying to find the side, you'd do the opposite of dividing, which is times)
10×sin(30)=5

Answer: 28
Step-by-step explanation:
Using the similarity rule we get the equation
(10+x)/(15+42) = x/42
420 + 42x = 57x
420 = 15x
x = 420/15 = 28
