Answer:
Step-by-step explanation:
Remark
They are asking you to combine like terms. The total should be 180.
Givens
2 angles
Total 180
Solution
8x - 3 + 4x + 3 = 180 The threes cancel. So add what's left. They are of opposite signs, so they cancel.
12x = 180 Divide both sides by 12
12x/12 = 180 /12
x = 15
You aren't sharing much information (no directions??).
If your triangle is a right triangle AND 5x-1 and 4x+1 represent the lengths of the 2 shortest sides, then the Pyth. Theorem tells us that
(5x-1)^2 + (4x+1)^2 = (hypotenuse length)^2.
We know that this could not be an equilateral triangle, because 5x-1 differs from 4x+1.
This could be an isosceles triangle if the third side were either 5x-1 or 4x+1.
Please be more specific about what you're supposed to do here.
Answer:
119.43cm^2
Step-by-step explanation:
The computation of the area of the shaded region is shown below:
As we know that
= Area of the rectangle - Area of the circle
where,
Area of rectangle is
= 132 cm^2
And, the area of the circle is
Now the area of the shaded region is
= 119.43cm^2
We simply deduct the area of the circle from the area of the rectangle so that the area of the shaded region.
