Answer:
Step-by-step explanation:
Let's solve for x.
−3x−4y=5
Step 1: Add 4y to both sides.
−3x−4y+4y=5+4y
−3x=4y+5
Step 2: Divide both sides by -3.
−3x

Answer:
32
Step-by-step explanation:
Angle E is congruent to angle C, so is the value required to make the sum of angles in triangle ABC be 180°.
∠E = 180° -118° -30° = 32°
The value of x is 32.
I am not for sure how to do this just yet when I figher it out I will try to help you.<span />
Answer:
x = 13.5
Step-by-step explanation:
We know that base angles of an isosceles triangle are equal. The base angles of the triangle are (4x)° each. The vertex angle of the traingle is (6x-9)°. So according to angle sum property of triangle,
![6x - 9 + 4x + 4x = 180](https://tex.z-dn.net/?f=6x%20-%209%20%2B%204x%20%2B%204x%20%3D%20180)
![= > 6x - 9 + 8x = 180](https://tex.z-dn.net/?f=%20%3D%20%20%3E%206x%20-%209%20%2B%208x%20%3D%20180)
![= > 14x - 9 = 180](https://tex.z-dn.net/?f=%20%3D%20%20%3E%2014x%20-%209%20%3D%20180)
![= > 14x = 180 + 9 = 189](https://tex.z-dn.net/?f=%20%3D%20%20%3E%2014x%20%3D%20180%20%20%2B%209%20%3D%20189)
![= > x = \frac{189}{14} = 13.5](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20x%20%3D%20%20%5Cfrac%7B189%7D%7B14%7D%20%20%3D%2013.5)
No, they are not the area of the first triangle is 24 because 1/2*b*h so 1/2*6*8 + 24 and the area of triangle #2 is 1/2*8*12 is 48.
Hope this helped!
