Answer:
The angle:
The supplement:
Step-by-step explanation:
By definition, if the sum of two angles is 180 degrees, then this angles are called "Supplementary Angles".
Let be:
the angle (in degrees) and its suppplement (in degrees).
Therefore, you can write the following equation in order to find the angle and its supplement:
Now, you must solve for "x". Then:
Then:
Answer:
Area of triangle= 35
x = 4
Step-by-step explanation:
The formula for area of rectangle = length x width.
Area of triangle = (1/2)bh
It's stated these two areas are equal:
(5)(3x - 5) = (1/2)(x + 3)(10)
Distribute on both the left side and the right side.
15x - 25 = (5)(x + 3)
15x - 25 = 5x + 15
Subtract 5x from both sides and add 25 to both sides.
10x = 40
Divide:
x = 4
Plug this back into the area of triangle:
= (1/2)(x + 3)(10)
= (1/2)(4 + 3)(10)
= (1/2)(7)(10)
= (1/2)(70)
= 35
Answer:
9 digits
Step-by-step explanation:
when doing multiplication with decimals the amount of digits after the decimal in the final product will be the sum of the amounts of digits after the decimal in the two numbers being multiplied together
For example, If you were to multiply 6.789 by 10.321 the answer would be 70.069269. There are six digits after the decimal because the numbers being multiplied each have three digits after their decimals
(If that makes sense. If not, I'm sorry)
