Answer:
θ = 38°
Step-by-step explanation:
The lower right triangle is congruent to the upper left triangle, so we have θ and 20° being the two acute angles in the triangle. The law of sines tells you ...
sin(θ)/9 = sin(20°)/5
sin(θ) = (9/5)sin(20°)
θ = arcsin(9/5·sin(20°)) ≈ 38°
___
Another solution to the triangle is θ = 180° -38° = 142°. The diagram clearly shows θ as an acute angle, so we take this second solution to be extraneous.
I believe the answer is 1.343 x 10^5
Answer:
See below
Step-by-step explanation:
<u>Angle 4 is exterior angle of the triangle and as per definition:</u>
<u>Angle 4 is supplementary with angle 3, they sum up to straight angle of 180°</u>

Step-by-step explanation:
Let's make a table:
Term 1: 3 toothpicks
Term 2: 4 toothpicks
Term 3: 5 toothpicks
Term 4: 6 toothpicks
Term 5: 7 toothpicks
Term N = N + 2 toothpicks
Unfortunately, you haven't shared "the following points."
The equation of a circle centered at the origin and whose radius is 10 is
x^2 + y^2 = 10^2.
