Answer 1

Which relationship is always correct for the angles x, y, and z of triangle ABC?

A triangle ABC has angle ABC labeled as y, angle ACB labeled as z, and the exterior angle at A labeled as x.
x + z = y
y + z = x
x + y + z = 180 degrees
x + y + z = 90 degrees

Hi

Answer 5

can you help me

Answer 6

how

Answer 7

i have a qusten

Answer 8

ok can you help me first

Answer 9

Recall, the sum of the three angles in a triangle is 180 degrees
and
the sum of the 2 angles that make up a straight line is also 180 degrees

Answer 10

Ah thats what I thought I just wasnt sure

Answer 11

That missing angle at A is , 180 - y - z
and
the sum of that angle and x is 180, 180 = 180 - y - z + x

Answer 12

So it is x+y+z=180 right?

Answer 13

no, 180 = 180 - y - z + x

180 - 180 = x - y - z

0 = x - y - z

x = y + z

Answer 14

oh ok thanks
