Answer:
Well I’m not sure what you want but I’ll give you both,
The perimeter is 25 units
The area is 28.5 units ^2
Step-by-step explanation:
Well to find perimeter just count every unit which is what I did and got 25 units.
To find the area jsut split them into two shapes and find the area for both.
Triangle formula: bh/2
Rectangle: Lw
Well we have 3 for base and 3 for height.
3*3=9
9/2=4.5
4.5 is the triangle
We got 3 for width and 8 for length
3*8=24
24 is the rectangle
Add them up
24+4.5= 28.5
28.5 units
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1
So we first need to find the slope of the reference line.
m=(y2-y1)/(x2-x1)=(7-2)/(-1--5)=5/4
So the perpendicular line will have a slope of:
5m/4=-1
m=-4/5
So our perpendicular line so far is:
y=-4x/5+b, now we can use point (3,-1) to solve for the y-intercept, "b"
-1=-4(3)/5+b
-1=-12/5+b
-5/5+12/5=b
7/5=b
So the line is:
y=-4x/5+7/5 or more neatly
y=(-4x+7)/5
y=-0.8x+1.4
Answer:
54
Step-by-step explanation:
The sum of given angles must be equal to 360°
3x° + 2x° + 90° = 360°
5x + 90 = 360
5x = 270 divide both sides by 5
x = 54
Answer:
the slope equals 2. otherwise known as the coefficient of x.
