Answer:

Step-by-step explanation:

2 answer choices you can cross out are the ones that have a +2t. The question says "Dropping at a steady rate of 2 degrees Celsius"

So cross out B & C.

Now at the end it states " Temperature was colder than -4 degrees Celsius"

That means the equality part will be smaller. Since negatives would be smaller when a number like -2.

Answer is A

Answer:

x = $25.8^{o}$ and y = $51.4^{o}$

Step-by-step explanation:

Known that he sum of angles on a straight line is $180^{o}$ . From the diagram;

2y + x + y = $180^{o}$

x + 3y = $180^{o}$ ................ 1

Also,

2x + x + 2y = $180^{o}$

3x + 2y = $180^{o}$ .............. 2

Using the elimination method, multiply equation 1 by 3 and equation 2 by 1

3x + 9y = 540 ............ 3

3x + 2y = $180^{o}$ ............. 4

7y = 360

y = $\frac{360}{7}$

y = $51.4^{o}$

substitute the value of y in equation 1,

x + 3y = $180^{o}$

x + 3(51.4) = $180^{o}$

x + 154.2 = $180^{o}$

x = $180^{o}$ - 154.2

x = $25.8^{o}$

Thus, x = $25.8^{o}$ and y = $51.4^{o}$

Answer:

sin a=3/5

cos a=4/5

Step-by-step explanation:

sin A

AB(squared)=AC (squared)+CB(squared) AB(squared)=4(squared)+3(squared)

AB (squared)=16+9

AB (you must put a square root over AB)=25(remember 25 is now a square root)

AB=5

sin a=opposite/hypotenuse

=3/5

cos A

cos a=adjacent/hypotenuse

=4/5
