Answer:
b = 9√5 (see below)
Step-by-step explanation:
Using the Pythagorean Theorem, you can find the missing side. The two sides connect to the right angle are the legs, and the sloping side across from the right angle is the hypotenuse.
We know that:
a² + b² = c²
—where a and b are legs and c is the hypotenuse.
Plug in the known values:
a² + b² = c²
18² + b² = 27²
324 + b² = 729
b² = 405
√b² = √405
b = √81 √5
b = 9√5
Answer:
Step-by-step explanation:
point - slope formula: y - y1 = m(x-x1)
we need to find the slope ... or what is m ?
m = rise / run
m = y2 - y1 / x2 - x1
where the given points are (x1,y1) and (x2,y2)
m= 7-5 / 6-5
m = 2 / 1
m =2
now use either point and plug the slope and the point into the point-slope formula
y-5 =2(x-5) :)
