Find the value
x- 1/x​

the value of x-1/x is given down

Step-by-step explanation:

=(x+1/x)²=x²+1/x²+2

=(5)²=x²+1/x²+2

=x²+1/x²=25-2

=x²+1/x²=23 this is the answer

if u ask there how 25 came means there (5)² is that u should multiply 5×5 and u will get 25bas the answer

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
