The sum of the angles of any triangle is 180 degrees, so we get the equation:

$(70)+(60)+(8x+2)=180\\8x+132=180\\8x=48\\x = 6$

x = 6

Hope that helps!

The vertices of a triangle are p(3,7) Q(7,-6) R(-8,7). Name the vertices of the image reflected across the x axis

pantera1 [17]

Answer:

P'(3,-7) Q'(7,6) R'(-8,-7).

Step-by-step explanation:

Reflection across the x-axis

Given a point P(x,y), its reflection across the x-axis will map to point P'(x,-y), i.e., the y-coordinate gets inverted.

We are given the vertices of a triangle P(3,7) Q(7,-6) R(-8,7). The vertices of the image reflected across the x-axis are:

P'(3,-7) Q'(7,6) R'(-8,-7).

The new triangle has vertices P'Q'R'.

Which of the following ordered pairs could represent the x-intercept of a function?

bearhunter [10]

The answer is (15,0) because the format is (x,y) so (15,0) means that it is on the x axis only !
