The interior angles of a triangle must add to 180 degrees.
110+5x+2x=180
110+7x=180
7x=70
x=10
Then plug in the x value into each angle expression
5(10)=50 degrees
2(10)=20 degrees
Well it would just be 54 since you just need to move the decimal over by 1.
So 5.4x10= 54
Its the number that multiplies x
6.25
Answer:
Step-by-step explanation:
Ok so first you would have to distribute the first side (left of the equal sign) So you would get 5+10m. Then do the next side 1/2 times 8 equals 4 and 1/2 times 20 m. Which is 10m. So 4+10m and 5+10m there for it would be false. They do not equal the same.
The answer is no.
Explanation:
60/55=1.090
7/42=.166
Therefore,
60/55≠7/42
