Answer:
Supplementary angles add to 180 degrees.
Angles of a triangle add to 180 degrees.
So, the angles of this triangle are 2x, 3x, and 70.
This means we can have the equation: 5x+70=180, and 5x=110, meaning that x=22
Let me know if this helps!
Answer:
22
Step-by-step explanation:
So first things first we want to find the angle on the bottom right
That angle is supplementary to the one that is equal to 110 meaning that together they will add up to equal 180
180-110=70
We know that the angles of a triangle will add up to equal 180 so we set up an equation
180=70+2x+3x and solve for x
step 1 combine like terms
2x+3x=5x now we have
180=70+5x
step 2 subtract 70 from each side
180-70=110
70-70 cancels out
now we have
110=5x
step 3 divide each side by 5
110/5=22
5/5 cancels
x=22
so we can conclude that x=22
