Answer:
x=30°
2x=60°
Step-by-step explanation:
Value of x°=x°/(2x°+x°)×90°
= 1/3×90°
=30°
Value of 2x°=30°×2
=60°

Answer:
The coordinate of
.
Step-by-step explanation:
To determine:
What is the coordinate of Z?
Fetching Information and Solution Steps:
- Points X and Y are on a number line
- point Y partitions
into two parts so that the ratio of the length of XY to the length of
is 5:7 - The coordinate of X is 1.3
- the coordinate of Y is 3.8
The distance
= 
As
Y is
of the way from
to 
So,
is
as big as 
Therefore,



Therefore, the coordinate of
.
