Answer:
Your answer is x=3
Step-by-step explanation:
So you have the equation 2x+5=11
First, subtract 5 from 5 and from 11.
Then you will cancel out the 5's.
After that, you should have "2x=6"
Now divide 2 from 2x and from 6.
Your answer is x=3
Answer:
45.6° (1 d.p)
Step-by-step explanation:
Using the cosine rule;
c = √( a² + b² - 2ab Cosx)
11 =√(8² + 15² - 2 (8) (15) Cosx)
11² = 8² + 15² - 240 Cosx
11² - 8² - 15² = - 240 Cosx
-168 = -240 cosx
cosx = 0.7
x = cos⁻¹ (0.7) = 45.57 ≈ 45.6°
