Question

choose yes or no to indicate whether each equation is correc
a. $m\angle abc = 97\degree$ \bigcirc yes
b. $m\angle abc = 83\degree$ \bigcirc yes
c. $m\angle 1 = 97\degree$ \bigcirc yes
d. $m\angle 1 = 135\degree$ \bigcirc yes

Explanation:

Response
Part a

Step1: Recall triangle angle sum

The sum of angles in a triangle is \(180^\circ\). In \(\triangle ABC\), we know \(\angle A = 52^\circ\) and \(\angle C = 45^\circ\).

Step2: Calculate \(\angle ABC\)

\(m\angle ABC=180^\circ - 52^\circ - 45^\circ = 83^\circ\). So \(m\angle ABC = 97^\circ\) is incorrect.

Step1: Use triangle angle sum

Sum of angles in \(\triangle ABC\) is \(180^\circ\). Given \(\angle A = 52^\circ\), \(\angle C = 45^\circ\).

Step2: Compute \(\angle ABC\)

\(m\angle ABC = 180^\circ-52^\circ - 45^\circ=83^\circ\). So this equation is correct.

Step1: Identify linear pair

\(\angle 1\) and \(\angle ABC\) form a linear pair, so their sum is \(180^\circ\).

Step2: Calculate \(m\angle 1\)

We found \(m\angle ABC = 83^\circ\), so \(m\angle 1=180^\circ - 83^\circ = 97^\circ\). This equation is correct.

No
