Oh i miss 6th grade im in 7th now lol and yes but i thank number 2 is 3 cnts
Answer:
x=4/7
Step-by-step explanation:
6 - 2/3(x+5) = 4x
First I want to clear the fraction so I will multiply everything by 3
3*6 -3* 2/3(x+5) = 3*4x
18 - 2(x+5) =12x
Distribute
18 - 2x-10 =12x
Combine like terms
8 -2x = 12x
Add 2x to each side
8 -2x+2x =12x+2x
8 = 14x
Divide each side by 14
8/14 =14x/14
8/14=x
Divide top and bottom by 2
4/7=x
For this, we will be using Triangle Angle Sum Theorem (all interior angles in a triangle add up to 180°) for Triangle BCD. Since Angle CBD and BDC are congruent to each other and Angle BDA, we can solve for those two angles to get that angle. Our equation will look like this: 
Firstly, subtract 35 on both sides of the equation: 
Next, divide both sides by 2 and your answer will be 72.5 = x.
Since Angle CBD and BDC are 72.5°, this means that Angle BDA is 72.5° as well.
Answer:
x ≈4.244833711
Step-by-step explanation:
x^2=7^2+8^2-2(7)(8)(cos32)
Determine the powers
x^2=49+64-2(7)(8)(cos32)
Multiply from left to right
x^2 = 49+64 - 112cos32
x^2 = 49+64 - 94.98138677
Add and subtract
x^2 =113-94.98138677
x^2 = 18.01861323
Take the square root of each side
sqrt(x^2) = sqrt(18.01861323)
x = sqrt(18.01861323)
x ≈4.244833711
x^2 =113
