Kevin is planting a triangular garden where 2 sides of the garden come together at an angle of 35°. if 1 unknown angle in the triangle is 4 times as large as the second unknown angle in the triangle, what are the measures of the unknown angles in kevin's triangular garden?

a. the second angle is 105, and the third angle is 29°

b. the second angle is 140°, and the third angle is 35º

c. the second angle is 120°, and the third angle is 30°.

d. the second angle is 116, and the third angle is 29°

d. The second angle is 116, and the third angle is 29°

Step-by-step explanation:

second unknown angle be x

the other unknown angle = 4*x = 4x

x+ 4x + 35 = 180  {sum of all angles of triangle}

5x = 180-35 = 145

x = 145/5

x = 29

the other unknown angle = 4x = 4*29 = 116

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

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.
