Which set of sides would NOT make a triangle?

the 3rd one

Step-by-step explanation:

A) 12 cm, 7 cm, 5 cm

Step-by-step explanation:

For the side lengths of a triangle to be true, the smaller side lengths can not add up to be smaller or equal to the larger side length. In this case, the smaller lengths are 7 and 5. Add them to get 12, the same side length as the largest side. The smaller sides (7 and 5) add to be equal to the longer side length, so these side lengths are FALSE. The other 3 sides of triangles are TRUE.

Hope it helps!

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
