Pythagorean theorem: a^2 + b^2 = c^2
The hypotenuse is always the c in the equation.
If the two side lengths they gave you are not the hypotenuse, then enter
4.5^2 + 5.6^2 in the calculator, then find the square root of that. :-)
All triangles add up to 180 so it’s 20°
No because 3 time 4 is 12 and 5 minus 12 does not equal -3
Answer:
25
Step-by-step explanation:
let x = 36
y = 9
x2 = 100
y2 = y2
y : x :: y2 : x2
We know,
Product of means = Product of extremes
That is,
y(x2) = x(y2)
Substituting the values,
9(100) = 36(y2)
=> 36(y2) = 900
=> y2 = 900/36
=> y2 = 25
so when x = 100, y =25
2(x + 5) = 3(x - 2)
<em><u>Distributive property on both sides.</u></em>
2x + 10 = 3x - 6
<em><u>Add 6 to both sides.</u></em>
2x + 16 = 3x
<em><u>Subtract 2x from both sides.</u></em>
x = 16 (This is your answer.)
