Answer:

-m + 2n - 2

Step-by-step explanation:

R - [S + T]

Since we know R = 11 - 2m, S = n + 5, and T = -m - 3n + 8,

we can substitute them in.

Replacing R,S and T

11 - 2m - [n + 5+-m - 3n + 8]

Combine inside the brackets

11 - 2m - [n - 3n-m +5+ 8]

11-2m -[ -2n -m +13]

Distribute the minus sign

11-2m - -2n --m -13

11-2m +2n +m -13

Combine like terms

m-2m +2n +11 -13

-m +2n -2

Find the value of x in the given

Dima020 [189]

Answer:

x = 6.0

Step-by-step explanation:

As the given triangle is a right-angled triangle, we can use the trigonometric ratios to find the required length.

In the given triangle

Hypotenuse = 10

Perpendicular = x

Angle = 37°

As we know the value for perpendicular and hypotenuse, sine will be used.

$sin\ 37 = \frac{Perpendicular}{Hypotenuse}\\sin\ 37 = \frac{x}{10}\\0.6018 = \frac{x}{10}\\x = 0.6018*10\\x = 6.018$

Rounding off to nearest tenth

x = 6.0

Hence,

x = 6.0
