The measure of angle G, m ∠G, is 42°. The correct option is the second option 42°
<h3>Calculating the measure of angle in a Triangle</h3>
From the question, we are to determine the measure of angle G
From the given information,
Angle L and angle I are congruent.
That is,
∠L ≅ ∠I
Angle J and G are congruent
That is,
∠J ≅ ∠G
Also,
Angle K and angle H are right angles
∠K ≅ ∠H = 90°
Since ∠K is a right angle,
Then,
m ∠J + m ∠L = 90°
Also,
Since ∠H is a right angle,
Then,
m ∠G + m ∠I = 90°
From the given information,
m ∠L = 48°
From m ∠J + m ∠L = 90°
m ∠J + 48° = 90°
m ∠J = 90° - 48°
m ∠J = 42°
But,
Angles J and G are congruent
Therefore,
m ∠G = 42°
Hence, the measure of ∠G is 42°
