.help me please
i accidentally pressed -4 btw

hint: the answer is not 3

-8

Step-by-step explanation:

All triangle angles must add up to 180.

If we look at the triangle, it has the angles of 40 degrees, and a right angle (90). If we add those together, we get 130.

So that means the top angle must be 50 degrees. Because 40+50+90=180.

So if the top angle is 50, the the other side must be 130. Again, because that is a 180 degree angle, going straight up.

So if we need to get 130, and the answers are not -4 or 3. Then the answer must be -8. Because 138+(-8)=130. Boom.

Hope this helped in some way. Stay safe, and have a good day!

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°

positive
