Pls fast I need help pls

ok so u know that all triangles in the inside are equal to 180

Step-by-step explanation:

1. 180-162= 18 angle a is 18, now to solve for b 180-122-18=40, angle b is 40

2.180-171=9 angle a is 9, now to solve for b 180-128-9=43, angle b is 43

3.180-35-22=132 angle c is 132, now to solve for angle d 180-22=158, angle d is 158

4. 180-20-29=131 angle c is 131, now to solve for angle d 180-20=160, angle d is 160

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
