The vertices of a triangle are P(-1, 2), QC-1, 7), and R(1,-1).

Name the vertices of
image reflected in the line y = x.
Oa P(2, 1), (7, 1), and R(-1, -1)
Ob. P(2, -1), (7, -1), and R(-1, 1)
Oc. P(-2,-1), (-7, -1), and R(1,1)
Od. P(-2,1). 9(-7, 1), and R(1.-1)

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.
