Answer:
The sum of the measures of the angles in a triangle is equal to 180 degree.
In triangle FGH;

or

Substitute the given values from the given figure we have;


Simplify:

Given that:
Using Cosine ratio:

In a given figure:
Base = GH = x and Hypotenuse = FH = y = 80 cm
Then;

or
cm
Therefore, the value of :

x = 43.57 cm
y = 80 cm
Answer:
Multiply 25.3 by 11.7, to get the answer of 296.01
Answer:
Samantha's age = 27 years
Step-by-step explanation:
As Samantha is one year less than twice her brother Jack’s age.
As the sum of their ages is 41.
Thus, the equation become
x+2x-1 = 41
3x-1 = 41
3x = 42
Dividing both sides by 3
x = 14
It indicates that Jack's age = 14 years
Therefore,
Samantha's age = 2x-1 = 2(14)-1 = 27 years
