2x+2x+60=180 because the angles have to add up to 180
So you have
4x+60=180
4x=120
x=30

Add me so when you get the equation you can ask me for help!!
Step-by-step explanation:
What is the equation
Answer:
A=81
Step-by-step explanation:
the first bullet is harder, but stuff you'll need to know eventually. The second bullet is SUPER simple.
a²+b²=c².
- One way you can do it; we know that c²=225, so find the square root of that. (it's 15). we also know that either a² or b² is 144. so now we square root that. (its 12). so we know that 15²-12²=b². or that 15²-12²=b². it doesn't matter if it's a or b. pick whichever one you want. plug one if the equations in, and you'll get 81.
- Second way you can do it, which is easier. 225-144=81. this is the same as above, but skipping steps. good for simple math, but later on with harder math it might make things confusing.
It would be: (2x⁵)³ = 2x¹⁵
So, Your Final Answer would be 2x¹⁵
Hope this helps!
Answer:
Step 1: Simplify both sides of the equation.
4(1−x)+2x=−3(x+1)
(4)(1)+(4)(−x)+2x=(−3)(x)+(−3)(1)(Distribute)
4+−4x+2x=−3x+−3
(−4x+2x)+(4)=−3x−3(Combine Like Terms)
−2x+4=−3x−3
−2x+4=−3x−3
Step 2: Add 3x to both sides.
−2x+4+3x=−3x−3+3x
x+4=−3
Step 3: Subtract 4 from both sides.
x+4−4=−3−4
x=−7
