Answer:
A
Step-by-step explanation:
In a right triangle, the side opposite to the 90 degree angle (here, side opposite to angle A) is known as the hypotenuse.
Also, the side that is "opposite" to the angle given (here side opposite is y to angle given 30 degrees) is the opposite side.
Since we want to find "opposite" and have "hypotenuse" , recalling trig ratios, we can say opposite/hypotenuse is the ratio SINE, so we can write:
We solve for y:
Since the answer choice has angles in radians, we recall 30 degrees is radians.
Thus, the correct answer is , or option A
C. carbon is found in all living things
a. heat is trapped in carbon
Step 1: Find the slope:
Step 2: Set up your equation using one of the points.
Using (5,6) we have .
Using (6,10) we have
Both of those equations would be correct.
Subtract.
1 1/3 - 2/3
Convert 1 1/3 into an improper fraction:
4/3 - 2/3
Subtract the numerators together:
2/3
So he read 2/3 more time on Saturday than on Friday.
