Answer:
The value of x = 20
Step-by-step explanation:
Given:
∠BOC = 3x - 15
∠COD = 2x + 5
Find:
The value of x
Computation:
⇔ ∠BOC + ∠COD = 90
⇔ 3x - 15 + 2x + 5 = 90
⇔ 5x - 10 = 900
⇔ 5x = 90 + 10
⇔ 5x = 100
⇔ x = 100 / 5
⇔ x = 20
The value of x = 20
To find the answer you must first make the equation which is
(5x)+85=150
subtract 85 from 150
(5x)=65
now divide 65 by 5
resulting in the answer
X=13
To check this
(5 x 13)+85=160
(5x)+85≤150
