When you don’t know the degree of a shape just use this form
180(n-2). Where n is the number sides of the shape.
There are 4 sides
180(4-2) = 180(2) = 360
So this shape is 360 degrees
120 + 120 + 60 +x = 360
300 + x = 360
X= 60
But as you can see that you don’t need this form for this question the alternate interior show you that the missing angles is 60
bearing in mind that perpendicular lines have negative reciprocal slopes, so
so we're really looking for a line whose slope is 3 and runs through (1,5)
Answer:
x=4
Step-by-step explanation:
x+3=7
subtract 3 from both sides
simplify
Answer:
x = 8
Step-by-step explanation:
Since B is between AC , then
AB + BC = AC , that is
2x + 1 + 3x = 41
5x + 1 = 41 ( subtract 1 from both sides )
5x = 40 ( divide both sides by 5 )
x = 8
