Question

3x-10 degrees and 2x+15 degrees are complementary find them

Answer 1

Here is your answer mate ..

1) 3x - 10 + 2x + 15 = 90

5x - 10 + 15 = 90

5x + 5 = 90

5x = 90 - 5

5x = 85

x = 85/ 5

x = 17

Now substitute x in the given angles

3(17) - 10 = 41

2(17) + 15 =49

so the angles are 41° and 49°

3)5x + 14 + x + 46 = 180

6x + 60 = 180

6x = 180 - 60

6x = 120

x = 20

Now substitute x in the given angles

5(20)+14=114

20+46 = 66

so the angles are 114° and 66° .
