I do not know the answer but download the app called Photomath and it will give you the answer
Answer:
Step-by-step explanation:
y and 76 are vertically opposite angles
x and z are vertically opposite angles
Linear pairs.
If sum of two adjacent angles are 180, then they are linear pair.
x & 76 are linear pairs
y & z are linear pairs
z & 76 are linear pairs
x and y are linear pairs
Solutions:
y = 76 { vertically opposite angles are equal}
x + 76 = 180 { linear pair}
x = 180 - 76
x = 104
z = x {Vertically opposite angles are equal}
z = 104
Answer:
Step-by-step explanation:
4(x+1)²=100
(x+1)²= 5²
(x+1)²- 5² = 0
(x+1-5)(x+1+5) = 0 by identity : a² - b ² = (a - b) (a+b)
(x - 4 ) (x+6) =0
x - 4 = 0 or x+6 = 0
x = 4 or x = - 6
10 times as much as 2000 is 1/10 of 200,000. I believe.
(21 3/4) / (2 1/2) =
(87/4) / (5/2) =
87/4 * 2/5 =
174/20 reduces to 8 7/10 (or 8.7)meters per hr
