I'd start by writing an equation for each of the right triangles. (Pythagorean theorem)
y² + 9² = z²
x² + z² = (4+9)²
4² + y² = x²
we want to find z so combine the equations by substituting the other variables x,y out.
substitute y² for (x² - 4²) in 1st equation.
(x² - 4²) + 9² = z²
now by rearranging the 2nd equation we can substitute x² for (13² - z²)
(13² - z²) - 4² + 9² = z²
169 - z² - 16 + 81 = z²
234 - z² = z²
234 = 2z²
234/2 = z²
117 = z²
√(117) = z
√(9*13) = z
3√(13) = z
13 goes in the box
13.41 is 13.406 rounded to nearest hundreth
Answer:
I hope I got this correct.
Step-by-step explanation:
Multiply the coordinates by 2.
P(4,8)
Q(-4,8)
R(0,-10)
For the future if you get stuck, multiply the coordinates by the dilation number.
It would be B. because it's just 7 times 1.5
Answer:
<T
Step-by-step explanation:
You can tell that the angles and length of the triangles are equal from the marks. For example, angle J has 2 lines on its angle so i looked for the other angle with 2 lines on it which happens to be angle S.
