Question

Two supplementary angles are (4x+15) and (x+5)°. Find the values of both the
angles.​

Answer 1

Step-by-step explanation:

supplementary angles are the angles whose sum is 180°

so (4x+15)+(x+5) = 180°

5x + 20 = 180°

5x = 160

x = 32

(4x +15) = (4×32 +15) = 143°

(x+5) = 32 +5 = 37°

are the angles

Answer 2

Answer:

32  and 143

Step-by-step explanation:

first 4x+15+x+5=180

4x+x=5x

15+5=20

5x+20=180

bring 20 to 180 which is 180-20=160

5x=160

5 divided by 160=32

x=32

4 x 32 +15 =143

32+5 = 37

143  37
