Answer:
The answer to your question is
A = 29.6°
B = 115.4°
C = 35°
Step-by-step explanation:
Process
1.- Use the Cosines law to answer this question
c² = a² + b² - 2abcosФ
Solve for cos Ф
cos Ф = (c² - a² - b² )/ -2ab
Substitution
cosФ = (7² - 6² - 11²) / (-2)(6)(11)
cosФ = (49 - 36 - 121) / -132
cos Ф = -108 / -132
cos Ф = 0.818
Ф = 35° = C
Find B
cos Ф = (b² - a² - c²) / (-2ac)
cos Ф = (11² - 6² - 7²) / (-2)(6)(7)
cos Ф = ( 121 - 36 - 49) / -84
cos Ф = 36 / -84
cos Ф = -0.429
Ф = 115.4° = B
2.- Find a
The sum of the internal angles in a triangle equals 180°
A + B + C = 180
A + 115.4 + 35 = 180
A = 180 - 115.4 - 35
A = 29.6°
Answer:
3/32
Step-by-step explanation:
Whatever you do to y always happens to x right? I'm REALLY new to this question so i'm not really sure so wait for more responses if needed.
To solve each inequality, we can use different operations or transposition to simplify the equations or expressions given.
1. m - 7 < 6 m < 13
2. x + 4.5 ≥ 5.5 x ≥ 1
3. p + 12 > 9 p > -3
The answer is actually 23.99
After the decimal place, it goes: tenths, hundredths, thousandths, etc.
Simplify 2/3 - 1/7 to 11/21
10/21 + 11/21
Simplify
The answer is 1.
