OK so I can't figure this out please help and I have to do 3 of the same type question so please explain how to do it thank you

I don't believe there is an answer to this.

Step-by-step explanation:

How it would usually go is you find the square root of both sides when it is simplified to this point. However, as -9 is negative, it has no square root.

If -9 were positive, however, the square root would be 3 and the question would look like this:

v = 3

Thus, your answer would be 3.

However, they may have given you a way to do this, so this is only what I think based off the experience I have atm.

I'm so sorry if I'm wrong, but would it be -3?

Step-by-step explanation:

I'd say its -3 because you would get v by itself, right?

So you square both to get v = -3

Again, srry of I'm wrong!

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°
