M1=35°
m2=65°
m3=29°
m4=115°
m5=65°
m6=36°
m7=144°
Ok so a) is integers
And b) is 21
Explaining for B
From 1-3 he added 2
From 3-6 he added 3
From 6-10 he added 4
From 10-15 he added 5
So we r gonna continue the sequence by adding 6
15-21 we added 6
Answer:
-w − z = <4, -7>
z − w = <6, 1>
w − z = <-6, -1>
Step-by-step explanation:
Answer:
sum of area of All six faces of cube is it's total surface area
Step-by-step explanation:
surface area of a cube =6*area of faces =6*(side) square
Answer:
The equation of the line is x = 2
Step-by-step explanation:
* It is a coordinate geometry problem.
We need to find the equation of a line with undefined slope.
* The slope is undefined
The line passing through point (2 , 5)
* The rule to find the slope is 
The slope is undefined if 
That means the line passing through points have same x-coordinate
That means the line is vertical
* ∵ The line passing through point (2 , 5)
∵ The slope of the line is undefined
∴ All the points on the line have x-coordinate = 2
∴ The equation of the line is ⇒ x = 2
* The answer is x=2
