3. in a triangle, two angles have measures of 45°
and 85°. what is the measure of the third angle in
this triangle?

50 degrees

Step-by-step explanation:

let angle be x

45 + 85 + x = 180  (angle sum property)

x=180-130

x=50 degrees

3rd angle=x=50 degrees

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
