Answer:
Step-by-step explanation:
We require to find the third side of the triangle.
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x represent the third side, then
x² + 7² = 8², that is
x² + 49 = 64 ( subtract 49 from both sides )
x² = 15 ( take the square root of both sides )
x = 
Thus
sinΘ = 
=
Answer:
c because it will be half of it meaning you have to multiply rhem
Answer: (7x + 8)³ ↔ the cube of the sum of 7x and 8
7(x + 8)³ ↔ 7 times the cube of the sum of x and 8
7x³ + 8 ↔ 8 added to the product of 7 and x cubed
(7x)³ + 8 ↔ 8 added to the cube of 7x
Step-by-step explanation:
(7x + 8)³ ↔ the cube of the sum of 7x and 8: for this case you will find that the values are into the parenthesis, then for each value apply the same exponent because of that all the values into the parenthesis are elevated to the cube,
7(x + 8)³ ↔ 7 times the cube of the sum of x and 8: in this example the 7 is multiplying all the values into the parenthesis, then you can find six times the sum of x and 8 elevated to the cube, also keep in mind that exponent which is 3 only apply to the values which are into the parenthesis and this values are the x and 8
7x³ + 8 ↔ 8 added to the product of 7 and x cubed: for this equation, you will find that 7 is multiplying to the x elevated to the cube after that, the 8 is added to this product.
(7x)³ + 8 ↔ 8 added to the cube of 7x: this final we can see that the values into the parenthesis are elevated to cube, the values are 7 and x, after this equation the 8 is added to the product.
