In a certain triangle x, y,z represents side lengths if x=7 and z=5 what must be true about y

Step-by-step explanation:

Given

Required

What must be true about y?

To answer this, we first calculate the range as follows;

and

For Minimum, we have:

For Maximum, we have:

The values of y are then bounded by the following:

This gives

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
