y = sqrt(9 * 16).
This formula is derived because of similar parts of similar right triangles.
It is called the geometric mean which you can google for right triangles that share a common side.
y = sqrt(144)
y = 12
D is the only possible answer.
=============
x = sqrt(9^2 + 12^2)
x = sqrt(81 + 144)
x = sqrt(225)
x = 15
=============
z = sqrt( (9 + 16)^2 - 15^2)
z = sqrt( 25^2 - 15^2)
z = sqrt(625 - 225)
z = sqrt(400)
z = 20
Answer D
z =
Answer:

Answer:
7m
Step-by-step explanation:
product means multiplication
7×m = 7m
Based on the information given the percent of the total cost of the bike has Wu saved is 30%.
Using this formula
Total cost percentage=Amount saved/Cost×100
Where:
Amount saved=$75
Cost =$250
Let plug in the formula
Total cost percentage=$75/$250×100
Total cost percentage=30%
Inconclusion the percent of the total cost of the bike has Wu saved is 30%.

Answer:
d = 36°
Step-by-step explanation:
If ∠1 ≅ ∠2, thia means both angles are the same.
Given m∠1 = 3d + 2 and m∠KHG = 70
Substitute m∠KHG = 70 = m<1 into the expression to get d
m<1 = 180-m∠KHG
m<1 = 180-70
m<1 = 110
110 = 3d+2
subtarct 2 from both sides
110-2 = 3d+2-2
108 = 3d
rearranging
3d = 108
Divided both sides by 3;
3d/3 = 108/3
d = 36°
