Respuesta :

4. angle1 and angle2 are complementary.

So,

x+3x+30=90

4x=60

x=15°

5. angleZ is liner angle,

Z+43=180

z=180-43=137°

6. The sum of two angles,

53°+127°=180°

so,

These two angle are supplementary angles.

7. The sum of these 2 angles,

34°+56°=90°

so,

These two angle are complementary angles.

8. The two angle are equal =67°

So,

answer is neither.

Step-by-step explanation:

4.x=15°

because the two angels are complementary.

5.z=137°

because Zis a liner angle

6. complementary angles

because the sum of the two angels are 90°

7. supplementary angle

because the sum of the two angels are 180°

8. neither

because the angels are same
