Answer:
m<10 = 65°
Step-by-step explanation:
I. Given m<18 = 46deg, m<13 = 69deg and m<10 = x
The degree is less than 90deg, so this triangle is acute triangle.
Sum of degree inside of triangle is 180°
So 46 + 69
= 115
Find x by
180 - 115 = 65
So m<10 = 65°
Hope that help :)
It's called a linear equation because the linear equation formula is y= mx+b, so they just changed the m to an a
x+4=3x
first subtract x from both sides(x-x and 3x-x)
4=2x
Now divide 2 from both sides (2x/2 and 4/2)
2=x
So x=2
