Im pretty sure that the answer is A.18 because it goes into all of the numbers :)
Answer:
35 days
Step-by-step explanation:
All you need to do is find a fraction that is proportional to the first, with a denominator of 49:
So you all you do is move the 49 to the other side of the equation. How do you do this? Multiply both sides by 49 (cross multiply):
So Teddy will work 35 days out of 49 days.
Using the circle theorems, we have proven that m ∠RTW = 15°
<h3>Circle theorems </h3>
From the question, we are to prove that m ∠RTW = 15°
In the given diagram,
measure of arc ST = 30°
∴ m ∠SRT = 30°
m ∠SRT = ∠T + ∠W ( <em>Exterior angle of a triangle equals the sum of the two remote angles</em>)
Also,
∠T = ∠W (<em>Radii of the same circle</em>)
∴ m ∠SRT = ∠T + ∠T
m ∠SRT = 2 × ∠T
30° = 2 × ∠T
∠T = 30° /2
∠T = 15°
∴ m ∠RTW = 15°
Hence, we have proven that m ∠RTW = 15°
