Answer:
The value of x = 9
Step-by-step explanation:
Given the angles of the triangle
We know that the sum of angles of a triangle is 180°.
Therefore,
(13x+2)° + (5x-7)° + (3x-4)° = 180°
13x+2 + 5x-7 + 3x-4 = 180°
21x + 2 - 11 = 180°
21x - 9 = 180°
21x = 180° + 9
21x = 189
divide both side sby 21
21x/21 = 189/21
x = 9
Therefore, the value of x = 9
Answer:
324 square meters
Step-by-step explanation:
Hey there!
The surface area of a shape is the area of all the surfaces added up
The side surface area is 48 since 16 x 3 is 48. Since there are two side areas, we need to multiply 48 x 2 is 96
Now we need to do this for the other sides
the bottom and top areas are 96 square meters each so we multiply 96 by 2 which is 192
The front and back faces have an area of 18 square meters so we multiply 18 by 2 since there are two faces which are 36
Now we add all the values: 96+192+36 which is 324
So the surface area of the prism is 324 square meters
