Answer:
x = 125
Step-by-step explanation:
all of the angles in a triangle must add up to 180, so 25 + 30 + x = 180. you can subtract 25 and 30 from both sides and you are left with x = 125.
hope it helps!
Last option - angle BAF and FAD
This is a rhombus and in any rhombus, the diagonals intersects in the middle and they are perpendicular:
So all 4 triangles are right triangles and the sides are the hypotenuses.
1st) Calculate the sides: hypotenuse² = 3² + 4² = 25, and hypotenuse = 5
The area of each right triangle is (4 x 3)/2 = 6 units²
And the area of the 4 right triangles = 4 x 6 = 24 init²
Answer:
Removing the perfect square 4 in 12 we get 2√3
Step-by-step explanation:
The square root of 12 is
√12 = √(4 x 3)
√12 = 2√3.
There's no special trick here, but it's usually easy to check whether a small number is divisible by 4. Keep this in mind when looking for factors.
Removing the perfect square 4 in the square root of 12 we get 2√3.
Here 4 is a perfect square it can be written as
√4 =√2^2
√4 =2
Answer:
27
