Answer:
Step-by-step explanation:
Equation:1
Equation:2
Solving Equation:1
Subtracting 'y' from both the sides:
Putting 'x' in Equation :2
Adding '4' both the sides
Putting the value of 'y' in equation:1
The solution is:
Answer:
Exterior angle = sum of opposite interior angles
Step-by-step explanation:
40 - 4 = 36
average = 36/9 = 4
answer
average number of members who joined the math club is 4 per month
The given ratio of the sides of the triangles is 4:10:7. Let the sides be 4x, 10x and 7x .
And given perimeter is 252 meters .
Perimeter is the sum of all sides. So we get
Dividing both sides by 21
So the sides are
D= diagonal= 25 in
w= 15 in
A= w√(d^2﹣w^2)
A= (15)√(25^2 - 15^2)
square in parentheses
A= (15)√(625 - 225)
subtract in parentheses
A= (15)√(400)
take square root of 400
A= (15)(20)
A= 300 in^2
ANSWER: The area is 300 inches squared
Hope this helps! :)
