<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 8x - 6
f(1/2) is x = 1/2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(1/2) = 8(1/2) - 6
- Multiply: f(1/2) = 4 - 6
- Subtract: f(1/2) = -2
The value of Tan 3.4 is 0.059410947 rounded off to four decimal places would equal to 0.0594, letter B. This is your answer if your calculator is in the degree mode.
Tangent or Tan is one of the trigonometry functions. It represents TOA in the sohcahtoa mnemonic which means Tan = Opposite / Adjacent
A) (5s + 2 / 4) x (4) = Perimeter
B) ( s + 9) x (2) + ( 3s - 5 ) x (2) = Perimeter
C) 22 + 48 = 70
Answer:
50 degrees
Step-by-step explanation:
We know that an inscribed angle in a circle is 1/2 the arc that it inscribes. So, therefore the arc is inscribed by the 25 degrees is 50. Assuming that the center of the circle is O, the center angle will be the arc measure. Knowing this, angle a is 50 degrees. If you're curious about all these theorems, they can be proved using similar triangles.
fyi, using the same logic, angle b is 25 degrees
