a = 2c - 8
Step-by-step explanation:
Topic: Algebra
A rational number stops and can be turned into a fraction and doesn’t repeat while an irrational number does the opposite
The answer is 5 because if you add 10 to -10 it is 0 then add the 5 more and it is 5.
Answer:
1st pic) 17.8
2nd pic) 16.8
3rd pic) 9.1
4th pic) 13.5
Step-by-step explanation:
<u>1st pic:</u>
(write equation) Cos 27 (cos 27 = 0.89) = 
(new equation) 0. 89 = 
(multiply 20 on both sides) 0.89 x 20 =
x 20
(solve) 17.8 = x
<u>2nd pic:</u> 
(write equation) tan 40 (tan 40 = 0.84) = 
(new equation) 0.84 = 
(multiply 32 on both sides) 0.84 x 20 =
x 20
(solve) 16.8 = x
<u>3rd pic:</u> 
(write equation) cos 55 (cos 55 = 0.57) = 
(new equation) 0.57 = 
(multiply 16 on both sides) 0.57 x 16 =
x 16
(solve) 9.1 = x
<u>4th pic:</u> 
(write eqaution) tan 42 (tan 42 = 0.90) = 
(new equation) 0.90 = 
(multiply 15 on both sides) 0.90 x 15 =
x 15
(solve) 13.5 = x
