goal: \i will be able to identify the angle relations to set up an equation to find the measure of each a
warm up: identify the relationship between of each angle below.
1.
a
75°
b
11x - 2
m ∠ a = _
m ∠ b = _
practice: set up an equation and solve
3.

Explanation:

Step1: Find m∠a (linear pair with 75°)

$m∠a = 180^\circ - 75^\circ = 105^\circ$

Step2: Find m∠b (alternate interior angle with 75°)

$m∠b = 75^\circ$

Answer:

m∠a = 105°
m∠b = 75°
