Answer:
x = 165, y = 15
Step-by-step explanation:
1. Well, what does supplementary mean? - The angles add up to 180°.
2. Let's form an equation: x + y = 180°
3. Let's say x is the larger angle and y is the smaller angle.
4. Let's form another equation: x = 150 + y
5. Put the two equations next to each other:
x + y = 180
x = 150 + y
6. We know what x is equaled to, so let's plug it into the first equation!
150 + y + y = 180
150 + 2y = 180
-150 -150
2y = 30
y = 15
7. Now, we know what y is, let's find x!
x + 15 = 180
-15 -15
x = 165
The square root of 7: 2.64575
-0.3
(-7/4)= -1.75
0.1
Square root of3: 1.73205
greatest to least: (-7/4), -0.3, 0.1, square root of 3, square root of 7
Answer:
7%, 0.28, 0.15, 13%, 21/100, 14/25

Hope this is right :)
Answer:
Step-by-step explanation:
Volume =base area* hight
The base is a right triangle so area is (18*2)/2=36/2=18
Vol =18*3 =54 ft^2
