Step-by-step explanation:
<h2>Given:</h2>
- angle 4 = x + 30
- angle 2 = 2x + 15
<h2>To find:</h2>
- the measure of angle 4 is ?
<h2>Solution:</h2>
angle 4 + angle 2 = 180° [corres. ∠s]
=> x + 30 + 2x + 15 = 180°
=> 3x + 30 + 15 = 180°
=> 3x + 45 = 180°
=> 3x = 180° - 45
=> 3x = 135°
=> x = 135°÷3
=> x = 45°
Now, putting the value of x in ∠4 and ∠2.
∠4 = x + 30
∠4 = 45° + 30 => 75°
Hence, the measure of ∠4 is 75°
∠3 = 2x + 15
∠3 = 2(45°) + 15 => 90° + 15 => 105°
Hence, the measure of ∠2 is 105°.

Answer:
B
Step-by-step explanation:
the are of the square would be: 4*6=24
the are of one triangle would be: (6*2)/2=6 (12 in total because there are two triangles
to find the whole area, you add 24 and 12 which is B) 36 meters squared
