Answer:
x = 31
Step-by-step explanation:
∠ A and ∠ B are vertical angles and are congruent, then
6x - 25 = 5x + 6 ( subtract 5x from both sides )
x - 25 = 6 ( add 25 to both sides )
x = 31
1060. trust me i’ve done that
1. Simplify 0.24 x 14.3 to 3.432.
= 3.432 ÷ 5.2
2. Simplify 3.432 ÷ 5.2 to 0.66.
= 0.66
If the temperature is the same in Farenheit and Celsius, the variable F is equal to the variable C in the equation. Thus, you'll just need to replace one or both variables in the original equation and solve for the single variable. I'll just use x as the variable here:
F = 1.8C + 32
x = 1.8x + 32
subtract x from both sides
0 = 0.8x + 32
subtract 32 from both sides
-32 = 0.8x
divide both sides by 0.8
-40 = x
So, since we know x = -40 degrees, we also know that F = -40° and C = -40° too.
Yes it is true:
(1 - cos^2 x) = sin^2 x Sqr.(1 - cos^2 x) = sin x and (-sinx) True, since sin x negative. Also, x terminates in quadrant 3 and 4. Hope this is helpful
