Answer:
45 cm
Step-by-step explanation:
Find LCM(15,9). First factor both numbers:
So,
This means that the length of the side of the smallest square area that can be covered by these tiles is 45 cm.
Practically, you can put 3 tiles in a row (to make 3 lenghts of 15 cm each that add up to 45 cm) and put such 5 rows (to make 5 lengths of 9 cm that add up to 45 cm).
The ladder is making a right triangle so just use sin, cos, and tan to find either of the unknown angles.
(a) Using sin, you can find the missing angle and come up with the equation sin<span>ø = 9.2/10
</span><span>ø=80 degrees
</span>(b) Using a different triangle where the height of the building is unknown but all the angles are known. You can use cos to find the length of the base of the triangle.
cos75=x/10
x=9.2 ft
Answer:
18,80,82
Step-by-step explanation:
82^2= 6724
18^2+ 80^2= 6724
The square of the largest number is equal to the sum of the squares of the two smaller numbers.
