Answer:
Step-by-step explanation:
step 1
Find the measure of angle C
Remember that the sum of the interior angles of a triangle must be equal to 180 degrees
so
A+B+C=180°
we have
A=57°
B=37°
substitute
57°+37°+C=180°
94°+C=180°
C=180°-94°=86°
step 2
Find the measure of side c
Applying the law of sines
substitute
The area of any triangle = (1/2) x (length of the base) x (height)
2.5 centimeters = 0.025 meter
The area of the sail is (3.75) = (0.5) x (0.025) x (height)
Multiply each side by 2 : (7.5) = (0.025) x (height)
Divide each side by 0.025 : (7.5)/(0.025) = height =<em> 300 meters</em>
The situation is stupid, but the math is bullet-proof.
Shorter side: 130ft
longer side: 260ft
greatest possible area: 33800ft^2
basically get the equations for area and perimeter which will be
A: lw (length x width)
P: l + 2w
Substitute them into eachother and you get the equation:
-2w^2+520w = A
find the vertex of this parabola which will give you the greatest width which is 130m
Then u can find length and area from this width
17 are older than 16 years old and 12 are taller than 170 cm
Step-by-step explanation:
27x² = 3*3*3*x*x
45x³y² = 3*3*5*x*x*x*y*y
Now
GCF = 3 * 3 *x * x = 9x²
