Question

Find the value of x if the given angles are complement (2x+50) and (x+4)

Answer 1

HERE'S THE ANSWER MATE

2X + 50 + X + 4 = 90

3X + 54 = 90

3X = 90 - 54

3X = 36

X = 36 / 3

X = 12

1ST ANGLE = 2 × 12 + 50 = 12 + 50 = 62

2ND ANGLE = 12 + 4 = 16

Answer 2

complementary angles= sum of 90°

so, (2x+50)+(x+4)= 90°

2x+x +50+4. =90°

3x+54. =90°

3x=90°-54

3x=36

x=36/3

x=12

first digit=(2x+50)

=2×12+50

= 74

second digit= (x+4)

= 12+4

=16

sum of 74+16= 90

hence, proved!

Hope this helps you!
