Question

Find the value of x
H E L P​

Answer 1

Answer:

from my pic below,

you know that ∠ABC = 90°.

90° = (x+15)° + (3x - 17)°

      = x +15 +3x - 17

      = x +3x + 15 - 17

      = 4x - 2 .

90 +2 = 4x

92 = 4x

92/4 = x

23 = x

∠ABD = 23 +15

          = 38°

∠DBC = 3 × 23 - 17

          =  52°

Answer 2

Step-by-step explanation:

x+15+3x-17=90°

4x-2=90

2 (2x-1)=90

2x-1=45

2x=45+1

2x=46

x=23
