Answer:

Step-by-step explanation:

1) Perimeter of a plane shape is the distance round the shape. The formula for the perimeter of a square is expressed as

Perimeter = 4 × length of one side

Since the length of one side is given as 10 inches,

The perimeter = 4×10 = 40 inches.

2) the side lengths of the triangle are 2x -7, 5x -3 and 2x -2. The formula for the perimeter of a rectangle is expressed as

a + b + c

Where a,b and c are the length of the sides of the triangle.

Perimeter = 2x -7 + 5x -3 + 2x -2 = (9x -12) inches

3) if x=6, the perimeter of the triangle would be

9×6 -12 = 54 - 12 = 42 inches

Answer:

1) 40

2)9x-12

3)42

Step-by-step explanation:

1) A square has 4 sides, and if one side's length is 10, the perimeter (distance around the square) is 10 times 4=40

2) Simply add these values together to get 9x-12

3) Plug in 6 as x in 9x-12. (6*9)-12=54-12=42

When i am solving for the sides of a right triangle when will i use trigonometric functions
AnnZ [28]

Answer:

The ratios of the sides of a right triangle are called trigonometric ratios. We need to use trigonometric functions to find them when we don't have any angle other than 90 degree shown.

Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle.

However when we have one angle given with the 90 degree we can deduct without trigonometry but we would use all angles to find the hypotenuse or all angles to find the side of a right angle.

Alternatively, we cna do this with one given angle but if we have one, we might as well work out the other one without trigonometry and do a division with Sin = 25 (sin 35) sin 90  / sin 55

is one example when given the base 25ft that would find the hypotenuse or the length of elevation for buildings looking down or zip-wire questions.

Step-by-step explanation:

       A

       |  \

       l     \

4cm|        \ 5cm

       |          \

       |            \

   B | -  -  -  -  \ C      

          3cm

Suppose we wanted to find sin( A) in△ABC    

(The height of the wall in elevation questions would be used above the base shown 3cm at the start) Sin = 3 (sin 35)° sin 90°  / sin 55° to find the height side (4).

Sine is defined as the ratio of the opposite to the hypotenuse

sin(A) =  hypotenuse          ​= AB/BC        = 3/5

             / opposite

2. How many terms are there in the expression: 3a + 6
Aliun [14]

Answer: 2

Step-by-step explanation: That expression is a binomial in any case the terms in a polynomial are separated by a plus or minus sign (+,-) so you can determine the number of terms by counting how many number or variable are being separated (ex: 3a+a-1 would have 3 terms and be a trinomial)
