Angles in a triangle add up to 180 degrees
The value of x is 85 degrees
<h3>How to determine the value of x</h3>
The sum of angles in a triangle is 180 degrees.
So, we have:
x + 35 + 60 = 180
Evaluate the sum
x + 95= 180
Subtract 95 from both sides
x = 85
Hence, the value of x is 85 degrees

Y = -1/2x + 3
Why?
Looking at the line start where the line intercepts the y line, it goes down one over 2 and that’s your slope, the 3 is bc that’s where the line crosses the y line
The LCM is the smallest number that all of those numbers can divide into evenly. So the LCM of 3,9,12 is 1
Answer:
85
Step-by-step explanation:
i useed the formula LxWxH
The temperature of the ice cream 2 hours after it was placed in the freezer is 37.40 °C
From Newton's law of cooling, we have that
Where
From the question,
∴
Therefore, the equation becomes
Also, from the question
After 1 hour, the temperature of the ice-cream base has decreased to 58°C.
That is,
At time ,
Then, we can write that
Then, we get
Now, solve for
First collect like terms
Then,
Now, take the natural log of both sides
This is the value of the constant
Now, for the temperature of the ice cream 2 hours after it was placed in the freezer, that is, at
From
Then
Hence, the temperature of the ice cream 2 hours after it was placed in the freezer is 37.40 °C
