<u>Given</u>:
Given that the angles of the kite.
The opposite angles of the kite measures (3y + 14)° and (y + 50)°
We need to determine the value of y.
<u>Value of y:</u>
We know the property that the opposite angles are equal.
Thus, applying the property, we have;

Subtracting both sides of the equation by y, we have;

Subtracting both sides of the equation by 14, we get;

Dividing both sides of the equation by 2, we get;

Thus, the value of y is 18.
Between emma and dave, we have 7/10ths of the money
3x + 2x = 7/10
5x = 7/10
x=(7/10)/5
x= 14/100
Dave will get 28/100 or 7/25ths
Check : 30/100 Colin
42/100 Emma
+ 28/100 Dave
-----------
100/00
1 Hour is longest then 1 minute then 1 second is shortest
For this case by similarity of triangles we can use the following relationship:
(x) / (9) = (5) / (15)
We clear the value of x:
x = ((5) / (15)) * (9)
Rewriting:
x = (1/3) * (9)
x = 3
Answer:
The value of x for this case is:
x = 3
Answer: 84
Explanation:
Total for 5 tests = 80 x 5 = 400
Total for 4 tests = 84 + 75 + 81 + 76 = 316
5th score = 400 - 316 = 84
