Check the picture below.
bear in mind that, a perpendicular line stemming from the right-angle like so, creates three similar triangles, a
large one, containing the other two smaller ones, a
medium and a
small.
so.. .we can just use the medium and small proportions.
solve for "x".
Answer:
1: 90º
2: 25º
Step-by-step explanation:
<em>Hey there!</em>
Well we know that all the middle angles are 90º right angles,
so we can conclude that angle 1 is 90º.
All the angles in a triangle add up to 180 so we can set up the following,
65 + 90 + x = 180
Combine like terms
155 + x = 180
-155 to both sides
x = 25º
So angle 2 is 25º.
<em>Hope this helps :)</em>
Answer:
50
Step-by-step explanation:
22 for the long sides
22+22=44
3 for the short sides
3+3=6
44+6=50
Answer:

Step-by-step explanation:
Answer: The value of x is 2
Step-by-step explanation:
x + 7 =3x + 3
-x -x
7= 2x + 3
-3 -3
4= 2x
x= 2
