The length of the hypotenuse, line segment ac, in right triangle abc is 25 cm. the length of line segment bc is 15 cm. which is the approximate measure of angle acb? 31.0° 36.9° 53.1° 59.0°

53.1°

The correct answer is third option

Step-by-step explanation:

It is given that,he length of the hypotenuse, line segment AC, in right triangle ABC is 25 cm. The length of line segment BC is 15 cm

To find the measure of <ACB

From the given information we get BC is the adjacent side of angle C and hypotenuse = 25 cm

Therefore Cos C = Adjacent side/Hypotenuse

 = 15/25 = .6

C = Cos⁻¹(0.6) = 53.1°

Therefore angle ACB = 53.1°

The correct answer is third option

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

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.
