Question

Help me, it will mean a lot if u do :)

Answer 1

Tangent must be 90degree so
90-48=42degreeXZU

Answer 2

Answer: 57 degrees

Explanation:

Angle ZXY = Angle YZV = 75 degrees (Alternate segment theorem)

Since angles on a straight line add upto 180 degrees:

Angle UZX = 180 - ( 75 + 48) = 57 degrees

Note: 75 is Angle YZV and 48 is Angle XZY
