Evgen [1.6K]

Answer:

(3, 2)

Step-by-step explanation:

y = 3x - 7

2x + 5y = 16

Solve for x:

2x + 5(3x - 7) = 16

2x + 15x - 35 = 16

17x = 51

x = 3

Solve for y:

y = 3(3) - 7

y = 9 - 7

y = 2

(3, 2)

Find the surface area of each prism. Round to the nearest tenth if necessary while doing your calculations as well as in your fi
kakasveta [241]

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!

100 points! Mhanifa please help. Look at the picture attached. I will mark brainliest!
natima [27]

Answer: BC = 54  <kjm=44

Step-by-step explanation:

1st 0ne-

if you look at it as 2 triangles with D being the shared side- I can determine that the angles are congruent (by SSA theorem)

so

6x=9x-27  (by corresponding parts of congruent Theorem)

-3x=-27

x=9

BC- 9(9)-27= 81-27=54

2nd one-

J bisects KJM

4x+6=3x+10

x=4

3(4)+10= 22

4(4)+6= 22

KJM= 22+22= 44
