A △ Has to have 180º so 72+56 b would have to be appx. 52degrres
Answer:
the graph can be x-y=2
Step-by-step explanation:
Solve the following system:
{x + 7 y = 0 | (equation 1)
{2 x - 8 y = 20 | (equation 2)
Swap equation 1 with equation 2:
{2 x - 8 y = 20 | (equation 1)
{x + 7 y = 0 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x - 8 y = 20 | (equation 1)
{0 x+11 y = -10 | (equation 2)
Divide equation 1 by 2:
{x - 4 y = 10 | (equation 1)
{0 x+11 y = -10 | (equation 2)
Divide equation 2 by 11:
{x - 4 y = 10 | (equation 1)
{0 x+y = (-10)/11 | (equation 2)
Add 4 × (equation 2) to equation 1:
{x+0 y = 70/11 | (equation 1)
{0 x+y = -10/11 | (equation 2)
Collect results:
Answer: {x = 70/11
{y = -10/11
Altitude = 90* Angle
15^2+b^2 = 39^2
225+b^2 = 1521
1296 = b^2
36= b
15^2 + b^2 = 17^2
225 +b^2 = 289
64 = b^2
8 = b
36 + 8 = 44
39+17 = 56
56 is greater then 44
Triangle Inequality Theorem Proves
So QR = 44
I'm confused....so the numbers above are unnecceary?
