Answer:
340 units2
Step-by-step explanation:
draw perpendicular line from upper left corner of trapezoid to cut bottom line(=9) into two part having length 3 and 6. Now a triangle and rectangle are formed.
The triangle has base=3, angle 60 degrees and angle of 90 degrees.
Finding third angle:
180-60-90= 30
finding other two sides of triangle by using law of sines:
a/sinA=b/sinB
3/sin30=b/sin60
b=3sin60/sin30
b=3(0.866)/0.5
b=5.2
b is the perpendicular line we drew
a/sinA=b/sinB
3/sin30=c/sin90
c=3sin90/sin30
c=3(1)/0.5
c=6
c is the hypotenuse of the triangle
Now Finding the perimeter of base:
The perimeter of the base=sum of the lengths of sides.
p=6+9+6+5.2
=26.2
area of trapezoid:
A= (a+b)h/2
= (6+9)(5.2)/2
=39
total surface area of prism:
TSA= ph + 2A
where h is height of prism = 10
TSA= 26.2(10) + 2(39)
=340
Hence total surface area of the given prism is 340 units square!
Ok it’s 21 because meme kid said 9 + 10 so it’s 21 because add car and dog and it makes a 420 blaze it
Answer:
Undefined
Step-by-step explanation:
The formula for slope is 
So use the x's and y's from the given points to solve for the slope
(10, -6) (10, -6)
The slope for this line would be undefined because a number cannot be divided by 0
Answer:
Natalie got 3, Veronica got 9.
Step-by-step explanation:
N = Natalie
If Veronica got 3 times as many as Natalie, then she got 3N.
Add them together:
N + 3N = 12
4N = 12
N = 3
Therefore,
Natalie got 3 (N = 3)
Veronica got 9 (3N = 3 x 3 = 9)
Answer:
width = 6 and length = 8
Step-by-step explanation:
perimeter = 2*(length + width). (1)
and we have that length = 2 + width
in (1)
28 = 2 *(width + 2 + width)
14= 2*width +2
width =6
and so length will be 8
