Answer:
c ≈ 6.08 m
Step-by-step explanation:
Your question is how to solve for a missing side length of a triangle when given 2 sides length and an angle. The side length can be solved using the cosine rule . We use cosine rule to find the length of a side of a triangle when given two sides and an included angle.
The cosine rule formula for finding a side length are as follows
c² = a² + b² - 2ab cosC
b² = a² + c² - 2ac cosB
c² = a² + b² - 2ab cosC
Using cosine rule
c² = 4² + 3² - 2 × 4 × 3 cos 120°
c² = 16 + 9 - 24 cos 120°
c² = 25 - 24 (-0.5)
c² = 25 + 12
c² = 37
square root both sides
c = √37
c = 6.0827625303
c ≈ 6.08 m
Answer:
y = 13 - 4x
Why?
4y +y = 13
Subtract 4x from both sides
4x+y-4x = 13 - 4x
Simplify
Y= 13 - 4x
Have a good day
Answer:
Everything
Step-by-step explanation:
We can keep every things in the blank boxes.
CosB= 7/25
tanB= 24/7
sinB= 24/25
