Hey there! :)
Answer:
x = 3.
Step-by-step explanation:
Begin by setting up a ratio comparing the small triangle to the large triangle. Remember, combine the values of the parts of the sides given to find the total lengths of the sides:
2x + x + 5 = 3x + 5
4 + 3 = 7
Now, we can set up a ratio:
Cross multiply:
7(x + 5) = 4(3x + 5)
Distribute:
7x + 35 = 12x + 20
Subtract 7x from both sides:
35 = 5x + 20
Subtract 20 from both sides:
15 = 5x
Divide both sides by 5:
x = 3.
Answer: 4/3
Step-by-step explanation:
Answer:
x > -3.
Step-by-step explanation:
9+x>6
Subtract 9 from both sides:
x > 6 - 9
x > -3.
Answer:
Your answer is 29.
Step-by-step explanation:
pythagorean theorem: a^2+b^2=c^2
equation: 20^2+ 21^2=x^2
next, simplify it to 400+441=x^2 and you would get 841.
now we must find the square root of 841 to get 29
