I dont know foe suee

a = 98⁰

Step-by-step explanation:

According to the the triangle sum thereom, all angles in triangle add up to 180⁰.

m<a + m<b + m<c = 180⁰

m<a + 34⁰ + 48⁰ = 180⁰

m<a + 82⁰ = 180⁰

m<a + 82⁰ - 82⁰ = 180⁰ - 82⁰

m<a = 98⁰

Hope this helps, thank you :) !!

both equations and proportions are better.
