Answer 1

90 + 49 = 139

180 - 139 = 41
x = 41

Answer 2

So you are trying to find your missing angle which is represented by x

we know that when we see that red square in the corner of the triangle it is equal to 90°

then we are told the other angle measure is 49°

therefore we can subtract 49 from 90
90°-49°= 42°

x=42°
