Answer:
= 26/23
Step-by-step explanation:
The expression that represents the value of sin C - cos C is s-r
From the triangle ABC, since sin B = r and cos B = s.=, hence;
- Opposite side= r
- Adjacent side = s
- Hypotenuse = 1
If m<C is the reference angle, then;
Opposite side= s
Adjacent side = r
Hypotenuse = 1
Sin C = s and cos C = r
Hence the expression that represents the value of sin C - cos C is s-r

Tom did not break the 70mph speed limit of M1.
To know if Tom breaks the <em>speed limit </em>of the M1, we must first calculate Tom's speed and compare it to M1's speed limit.
Using the formula below,
- s = d/t............... Equation 1
Where:
- s = Tom's speed
- d = distance from Leicester to London
- t = time taken to travel from Leicester to London
From the question,
Given:
- d = 143 miles
- t = 8:25 to 10:15 = 2 hours 10 munites = (2+10/60) = (2+0.17)
- t = 2.17 hours.
Substitute these values into equation 1
- s = 143/2.17
- s = 65.899 mph.
Hence, Since Tom's speed is less than the M1 speed limit, Tom did not break the 70mph speed limit of M1.

Step-by-step explanation:
2 < x < 4 and 3 < y < 7
We have (2 + 3) < (x + y) < (4 + 7),
Therefore 5 < x + y < 11.
The largest integer value for
x + y is 10.
