D is the correct answer I think.
Answer:
x ≈ 7.7
Step-by-step explanation:
Using Pythagoras' identity on the right triangle on the right side
let the third side be y , then
y² + 4² = 10²
y² + 16 = 100 ( subtract 16 from both sides )
y² = 84
Using Pythagoras' identity on the right triangle on the left side
x² + 5² = y²
x² + 25 = 84 ( subtract 25 from both sides )
x² = 59 ( take the square root of both sides )
x = ≈ 7.7 ( to the nearest tenth )
Answer:
Step-by-step explanation:
Supplementary angles are angles equal to 180°.
Therefore:
Now that we have our equation, let's distribute the and the into the parentheses they are next to:
Combine like terms:
Subtract from both sides of the equation:
Divide by the coefficient of , which is :

Check your work by substituting into one of the equations above:
It's correct!
Answer:
To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply. The base and height of a parallelogram must be perpendicular.
