What is the value of x? enter your answer in the box. x = an equilateral triangle r t s with vertical base r t and vertex s is right of the base. side r t and t s and s r are labeled with single tick mark. angle r s t is labeled as left parenthesis 7 x plus 4 right parenthesis degrees. angle r t s is labeled as left parenthesis 8 y plus 12 right parenthesis degrees.

 x = 8

Step-by-step explanation:

Since, RTS is the equilateral triangle.

Thus, RT= TS = SR

And, ( By the property of the equilateral triangle.)

Here, Given  ∠ RST =  (7 x + 4)°

And, ∠ RTS = (8y +12)°

Therefore, (7 x + 4)° = 60°

⇒ 7 x = 56

⇒ x = 8

x=8

Step-by-step explanation:

Since, RTS is the equilateral triangle.

Thus, RT= TS = SR

And,  ( By the property of the equilateral triangle.)

Here, Given  ∠ RST =  (7 x + 4)°

And, ∠ RTS = (8y +12)°

Therefore, (7 x + 4)° = 60°

7 x = 56

x = 8

6e14 is the answer.

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.
