Answer: C) exactly one triangle
<u>Step-by-step explanation:</u>
Given: ∠A = 45°, ∠B = 65°, side c = 4 cm
By the Triangle Sum Theorem, ∠C = 70°
Now you have a proportion so you can use the Law of Sines to find the exact length of side a and of side b.
![\dfrac{\sin\angle A}{a}=\dfrac{\sin\angle B}{b}=\dfrac{\sin\angle C}{c}\\\\\\\dfrac{\sin 45^o}{a}=\dfrac{\sin65^o}{b}=\dfrac{\sin70^o}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csin%5Cangle%20A%7D%7Ba%7D%3D%5Cdfrac%7B%5Csin%5Cangle%20B%7D%7Bb%7D%3D%5Cdfrac%7B%5Csin%5Cangle%20C%7D%7Bc%7D%5C%5C%5C%5C%5C%5C%5Cdfrac%7B%5Csin%2045%5Eo%7D%7Ba%7D%3D%5Cdfrac%7B%5Csin65%5Eo%7D%7Bb%7D%3D%5Cdfrac%7B%5Csin70%5Eo%7D%7B4%7D)
Thus, there is exactly one triangle.
Answer:
(x + 3)² + (y - 2)² = 4
Step-by-step explanation:
The standard equation for a circle is
(x - h)² + (y - k)² = r²
where (h, k) is the center and r is the radius
-----------------------------
Plug in the givens
(x + 3)² + (y - 2)² = 2²
(x + 3)² + (y - 2)² = 4
Answer:
The answer to this problem is 32
Step-by-step explanation:
How to get this answer is u divide the base by the area of meters. so 276/12=32. Hope this helps and i hope its right!
