Hello. Firstly you have to remembet that the sum of the three angles in any triangle is 180grades
So, determining the constant (k) you will have:
2:9:1
2k+9k+1k=180
12k=180 180/12=k
k = 15
Multiply the constant by 180 and divide by the given ratio:
180*15 / 2
180*15 / 9 etc
then your angles are
2:9:1
24:108:12

Can a triangle with the angles of 0, 90 , and 90 be considered a triangle?

asambeis [7]

A "triangle" with the angles 0, 90, and 90 degrees cannot be considered a triangle since the two 90 degree angles make a right angle, and 0 degrees would mean a flat line. Rather it would resemble something like a straight U that is stretched sideways.

Answer:

58.2

Step-by-step explanation:

We can find the length of RS using similarity ratio

7/34 = 12/RS cross multiply expressions

7RS = 408 divide both sides by 7

RS = 58.2 approximately.
