Question

find the value of x for the angles 2 x minus 5 and x minus 10 are the complementary angles​

Answer 1

Answer:

2x-5+x-10=90

3×-15=90

3×=90+15=105

×=105/3=35

1stangle=2×-5=2(35)-5=70-5=65

2nd angle=90-65=25

Answer 2

Answer:

If they are complementary angles then if we add them, they are equal to 90°

Adding both the equations

2x-5 + x-10=90

3x-15=90

3x=105

therefore x=35
