Answer:
94°
Step-by-step explanation:
This is a quadrelateral, and so all the sides must equal 360.
Set the equation: F + 66 + 132 + 68 = 360
Isolate the variable F. First, simplify. Combine like terms: F + (266) = 360
Isolate the variable F. Subtract 266 from both sides:
F + 266 (-266) = 360 (-266)
F = 360 - 266
F = 94
94 is your answer.

Answer: X= 4 and angle B = 26
Step-by-step explanation: 5x-5=3x+13
Subtract 3x and add 5 to both sides. Divide both sides by 2.
Answer:
6 seconds
Step-by-step explanation:
<u><em>The question in English is</em></u>
An object is thrown from a platform.
Its height (in meters), x seconds after launch, is modeled by:
h(x)=-5x^2+20x+60
How many seconds after the launch does the object reach the ground?
Let
x ----> the time in seconds
h(x) ---> the height of the object
we have

we know that
When the object hit the ground the height is equal to zero
so
For h(x)=0
we have

The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
The solution is x=6 sec
The he object reach the ground at x=6 seconds
