Answer:
Question 1. Option (3) RT = 35°
Question 2. Option (3) y = 2
Step-by-step explanation:
By the definition of external angle, ∠PSY is the external angle formed by the secants PS and YS.
From the attached diagram.
Theorem says,
m(∠a) = °
Now we will apply this theorem in our question.
m(∠PSY) = 180° - [m(∠SMX) + m(∠MXS)]
= 180° - (95° + 45°)
= 180° - 140°
= 40°
Since m(∠PSY) = [By the theorem]
m(arc PY) = m(arc PW) + m(arc WY)
= (80 + 35)°
= 115°
Now m(∠PSY) =
40° = °
80 = 115 - RT
RT = 115 - 80
RT = 35°
Therefore, Option (3). RT = 35° is the answer.
Question 2.
By the theorem, every angle at the circumference of a semicircle, that is subtended by the diameter of the semicircle is a right angle.
Therefore, (53y - 16)° = 90°
53y = 90 + 16
53y = 106
y = 2
Therefore, Option (3). y = 2 is the answer.

<h3>Answer:</h3>
In this question, we're trying to find the probability of it being cloudy and raining.
In this case, we know that:
- Probability of it being cloudy is 30%
- Probability of it raining is 25% (this is necessarily not needed)
- If it's cloud, the probability of it raining is 45%
With the information above, we can find the probability.
We know that from a 100% scale, the chance of it being cloudy is 30%.
We know that if it's cloudy, the chances of raining is 45%
To find the probability of it being cloudy and raining, we would multiply 0.3 (30%) by 0.45 (45%)
Solve:
Your answer would be C). 13.5%
