Answer: y = -4
Step-by-step explanation:
4 (6) + y = 20
24 + y = 20
-24 -24
y = -4
Answer:
A) By using the Pythagorean Theorem, we will see that
. If we simplify it, we will find that the hypotenuse of Δ
B) approximately 
Step-by-step explanation:
A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!
***Pythagorean Theorem is 
B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be,
.

Hope you do well on the rest of your math problems :D
Answer:
f(5)=80
Step-by-step explanation:
5^2=5*5=25
(4/5)(25)=4(5)=20
12(5)=60
20+60=80

Given:
The sum of the angles in a hexagon is 720°.

To find:
(a) Equation to solve the value of x.
(b) The value of x.
(c) The measure of angle C.
Solution:
(a)
We have,

The sum of the angles in a hexagon is 720°.



Therefore, the required equation is
.
(b)
On solving the above equation, we get



Divide both sides by 3.


Therefore, the value of x is 42.29.
(c)
We need to find the measure of angle C.



Therefore, the measure of angle C is 126.87 degrees.
