In the figure below, the measure of < 4 is 130. what is the sum of the measure of < 2 and < 3

100 degrees.

Step-by-step explanation:

<4 and <2 are adjacent angles so

m <4 + m<2 = 180

m<2 = 180 - 130 = 50 degrees.

m<3 = m<2 ( opposite angles).

Sum of <2 and < 3 = 2*50 = 100 degrees.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
