Answer:
240 cm^2
Step-by-step explanation:
area of each triangle
=(10 x 7)/2 cm^2
=35 cm^2
area of four triangles
=35 x 4 cm^2
=140 cm^2
area of the square
=10 x 10 cm^2
=100 cm^2
area of the polygon
=(100 + 140) cm^2
=240 cm^2
First One:
-5(3m+6)=-3(4m-2)
-15m-30 = -12m+6
-3m = 36
m = -12
Second:
-7(k+9)=9(k-5)-14k
-7k-63 = 9k-45-14k
-7k-63=-5k-45
-2k=18
k=-9

Step-by-step explanation:
The ratio cosine tell us that
- In a right angled triangle, the cosine of an angle is the side adjacent to the angle divided by the hypotenuse of the triangle.
In other words,

The side adjacent to angle a is 9. The hypotenuse is 41.
So

Answer:
2/7
Step-by-step explanation:
by dividing both numerator and denominator by 5
