Perimeter is 25 solve for x

2x-8

2x+5

30-3x

The answers are   .

Step-by-step explanation:

Given:

Perimeter is 25.

2x-8

2x+5

30-3x

Now, to solve for

So, the first equation to solve:

Adding both sides by 8 we get:

Dividing both sides by 2 we get:

Then, the second equation to be solve:

Subtracting both sides by 5 we get:

Dividing both sides by 2 we get:

And, the third equation to solve:

Subtracting both sides by 30 we get:

Dividing both sides by -3 we get:

Therefore, the answers are .

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°

80 the answer is 80
