Answer:
x = 7
y = 26
z = 6
Step-by-step explanation:
First, we can use vertical angles to say the angle with measure 10x + 6 is equal to the angle with measure 16x - 36. Because of this, we can set up an equation to solve for x:
10x + 6 = 16x - 36
6 = 6x -36
6x = 42
x = 7
Next, we can realize the angle 10x + 6 and 4y are supplementary and add up to 180 because they form a straight line. We can set up and solve the equation:
10x + 6 + 4y = 180
We found x = 7, so we can plug that in:
70 + 6 + 4y = 180
76 + 4y = 180
4y = 104
y = 26
Now, we can realize that the angle 4y and 16z + 8 are vertical angles; this gives us the equation:
4y = 16z + 8
We found that y = 26, so we can plug that in to get:
104 = 16z + 8
16z = 96
z = 6
Answer:
B
Step-by-step explanation:
A=1/2*(10+20)*5
=1/2*30*5

7 1/2 x 3 3/4 x 2, to get the answer. The answer is
56 1/4 feet squared
1,615 - 53.60 = 1,516.4
1,516.4 rounded is 1,516.
1,516 is about 96% of 1,615.
100 - 96 = 4
4%
3/2.5 = 48/c
Cross multiply
3*c = 3c
2.5 * 48 = 120
3c = 120
3c/3 = 120/3
c= 120/3
c= 40
Answer: c = 40
