Answer:
x=3 y=4
Step-by-step explanation:
5(4)=20
4(3)= 12
20-12=8
4+3=7
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:
To find the acceleration we have its formula as
v-u/t where v is final velocity, u is initial velocity and t is time
So substituting the values,
0-40/5 m/s²
-40/5 = -8 m/s²
Thus the acceleration is -8m/s²
pls give brainliest for the answer
There is 100 cm in 1 meter so if thats true then you must take
345/100
and that should be your answer :)
