In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 88° more than the measure of the second angle Use the fact that the sum of the measures of the three angles of a triangle is 180° to find the measure of each angle
The measure of the first angle is º
The measure of the second angle is
The measure of the third angle is nº

Step-by-step explanation:

The measure of the second angle = n

The measure of the first angle = 2*n

The measure of the third angle = n + 88

n + 2n + n + 88 = 180

4n + 88 = 180

4n = 180 - 88

4n = 92

n = 92/4

n = 23

second angle =              23

First angle = 2*23=        46

Third angle = 23 +88 = 111

The total is 180

answer: b.36 feet

step-by-step explanation:

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.
