Answer: The area common to both triangle is 31.77 sq. cm.
Step-by-step explanation:
Since we have given that
30-60-90 triangles are placed.
So, the ratio of sides would be

Since Hypotenuse = 12 cm
So, it becomes,

So, Base would be

and Perpendicular would be

So, Area common to the both triangles would be

Hence, the area common to both triangle is 31.77 sq. cm.
Answer:
800,000,000 90,000,000 5,000,000 3,000 40 9
Step-by-step explanation:
Given:
perfect score- 100
number of questions of the test- 25
worth of each question- 4 points
Fred's score- 84
n- number of questions Fred had answered incorrectly.
solution:
solve for n
division sentence: (100 ÷ 4 ) - ( 84 ÷ 4 ) = n
(100 ÷ 4 ) - ( 84 ÷ 4 ) = n
25 - 21 = n
4= n
therefore, Fred had answered 4 test questions incorrectly.
