(AAA) Corresponding angles are congruent.
Therefore, the sides of the triangles are proportional:
cross multiply
use distributive property
subtract 100 from both sides
divide both sides by 100
--------------------------------------------------------------------------------------------
(SAS)
If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
Therefore we have the equation:
The perimeter of △PQR:
Substitute the value of y to the expression:

Step-by-step explanation:
4x - 5(x + 3) Remove the brackets. Watch the - sign and -5*3
4x - 5x - 15 Combine the xs
-x - 15
Answer:
11.46 I believe
Step-by-step explanation:
Well, the sum of all internal angles in a triangle, isosceles or whatever else, is always 180°, so the sum of all those three folks, will be 180 then
so.. hmmm let's say the smallest angle is "a" units
twice that is, 2*a, or 2a
25 larger than that? is well 2a + 25
so... the other two twin angles, are 2a+25 each
thus a + (2a + 25) + (2a + 25) = 180
solve for "a" to find the smalles one
what about the twins? well, each is 2a + 25
