Answer:
b² = a² + c² - 2ac cos B
Step-by-step explanation:
The cosine rule can be use when you are given three sides of a triangle and ask to find any angle or when you are given two sides and a included angles(the angle between the two sides given) and ask to find the length of a side.
The equation Sophia can use to solve for the side length(b) of a triangle when given two length and the included angle can be expressed below. Sophia was given two sides and an included angle and was asked to find a side length b.
For sides a, b and c the cosine rule can be represented below
a² = b² + c² - 2bc cos A
b² = a² + c² - 2ac cos B
c² = a² + b² - 2ab cos C
The equation required base on your question is
b² = a² + c² - 2ac cos B
Answer:
6 +67 _^76 + 9 x 2087 - 9012 = 1000
Step-by-step explanation:
98 + 2000 - 76 = 1000
Answer:
21 feet²
Step-by-step explanation:
To find the area of a composite figure, we can break the shape into pieces and solve for the area separately.
There are multiple ways to separate the figure, but for this explanation we will break it into two rectangles, 5×3 and 3×2.
The area of a rectangle can be found by multiplying the length and width of the shape. So for the left rectangle, we will multiply 5 by 3.
5 · 3 = 15
The area of our first rectangle is 15 ft².
Next, we will find the area of the right rectangle, by multiplying 3 by 2.
3 · 2 = 6
The area of the second rectangle is 6 ft².
Now we can add the areas, 15 and 6, together to find the total area.
15 + 6 = 21
The area of the figure is 21 ft².
I hope this helps ^^ Good luck ∩_∩
