Answer:
126
Step-by-step explanation:
Let x be the missing length
The triangles are similar:
● UE/140 = 45/x
From the graph we deduce that:
● UE = 140 - 90 = 50
Replace UE by its value
● 50/ 140 = 45/x
Switch x and 50
● x / 140 = 45/50
45/50 is 9/10 wich is 0.9
● x/140 = 0.9
Multiply 0.9 by 140
● x = 140 × 0.9
● x = 126
Answer:
q = ± 
Step-by-step explanation:
We are to solve for q in:
16pq² = 25
q² = 
= ±
= ± 
From general equation of a line;
y=mx+c
m=

m=

m=-1
y=-x+c
Finding value of c;
using point (-2,0)
0=-(-2)+c
c=-2
y=-x-2
The question would help if there were a picture of the problem
however I can say that it should always add up to 180 and subtracted by the interior sum
