Answer:

z-score = 0.741

Step-by-step explanation:

The provided information are:

Population mean (\mu) = 103

Population standard deviation (\sigma) = 2.7

Score (X) = 105

The formula to calculate the <em>z</em>-score is:

z=\frac{X-\mu}{\sigma}

The z- score can be calculated as:

z=\frac{X-\mu}{\sigma}\\z=\frac{105-103}{2.7} \\z=  0.741

Hence, the z-score is 0.741.

Prove that congruent triangles have congruent corresponding angle bisectors.
worty [1.4K]
When two triangles are congruent, everything in them is congruent (same). So, the angle bisector of one triangle is congruent to the corresponding angle bisector of the other triangle.
