Find the value of x. Part 1c
2 answers:
Answer: x = 11
<u>Step-by-step explanation:</u>
a) bottom triangle, bottom right angle: Using Linear Pair Postulate, 180° - 114° = 66°
b) bottom triangle, top angle: Congruent sides implies congruent angles = 66°
c) bottom triangle, bottom left angle: Using the Triangle Sum Theorem, 66° + 66° + y = 180° --> y = 48°
d) top triangle, bottom angle: Using Complimentary Angles Theorem, 90° - 48° = 42°
Congruent sides implies congruent angles:
42° = ∠2
42 = 2x + 20
22 = 2x
11 = x

Answer:
Step-by-step explanation:
Given that:
This implies that the level curves of a function(f) of two variables relates with the curves with equation f(x,y) = c
here c is the constant.
By cross multiply
From (2); let assume that the values of c > 0 likewise c < 100, then the interval can be expressed as 0 < c <100.
Now,
This is the equation for the family of the eclipses centred at (0,0) is :
Therefore; the level of the curves are all the eclipses with the major axis:
and a minor axis
which satisfies the values for which 0< c < 100.
The sketch of the level curves can be see in the attached image below.
