Answer:
x = 50
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 2 given angles in the lower triangle and subtract from 180 to find the third angle
third angle = 180° - (65 + 65)° = 180° - 130° = 50°
x = third angle = 50 ( vertical angles )
1.25 is the slope 5/4 rise over run
Slope intercept form is

where

is the slope
and

is the y-intercept
they give us that the slope is 2
so our

then to find

, we temporarily plug in the point they gave us for x and y
so

and solve for

3 = 2 + b
1 = b
so our

put this together and we get

as our answer
Answer:
x = 15 cm
Step-by-step explanation:
All the ratio of corresponding sides should be equal
10 corresponds to x
16 corresponds to 24
12 corresponds to 18
<em>Finding the ratio of the known pairs:</em>
<em>Similarly 10 is to x should be 2 is to 3. Finding x:</em>

So x = 15.
3 is the original number
You have to do reverse operations
23-11=12
12/4=3
