Given the measure of side a, b and c of the triangle, the measure of angle C to the nearest tenth is 104.5°.
<h3>What is the measured angle C?</h3>
From the law of cosines;
cosC = ( a² + b² - c² ) / 2ab
Where C is the angle C and a, b, and c are the three sides of the triangle.
Given the data in the question;
- Side a = 2
- Side b = 3
- Side c = 4
- Angle C = ?
Using law of cosine;
cosC = ( a² + b² - c² ) / 2ab
We substitute the values into the equation.
cosC = ( 2² + 3² - 4² ) / ( 2 × 2 × 3 )
cosC = ( 4 + 9 - 16 ) / ( 12 )
cosC = -3 / 12
cosC = -0.25
We find the inverse of cosine.
C = cos⁻¹( -0.25 )
C = 104.477°
C = 104.5°
Given the measure of side a, b and c of the triangle, the measure of angle C to the nearest tenth is 104.5°.

Answer:
y = 2x + 1
Step-by-step explanation:
The gradient of line A is
Parallel lines have the same gradient, so m = 2.
Substituting the coordinates of P into y = mx + c,
Answer:
I'm not sure why there's a plus at the end of the 11x, but i think the answer is 2 1/11
Step-by-step explanation:
We know that the group of friends has $285 to spend on parking and admission.
7.25 + 28.50(x) = 285
285 - 7.25 = 277.75
277.75 / 28.50 = 9.745…
x = 9
The maximum amount of people who can go to the park is 9 people.
