In the problem we’re supposed to find the value of x that makes ABC ~ RST I can’t figure it out can someone please help
1 answer:
Answer:
Step-by-step explanation:
if the triangles are similar then their sides are in proportion ( or you can think that they make equivalent fractions like 2/3 = 4/6 )
44/ (x+2) = 20/7 = 3x+1 /5 ( all of those are equivalent fractions)
use that is the same as a*d = b*c
is the same as 20(x+2) = 7*44
20x +40 = 308; subtract 40 from both sides
20x = 268; divide by 20 both sides
x= 13.4

Option d: Angle A is 30 degrees, BC is 5 units
Option e: AC is 8 units, BC is 6 units
Explanation:
The triangle ABC has a right angle at C.
The length of the hypotenuse is 10 units.
The image of the triangle with this measurement is attached below:
Option a: Angle A is 20 degrees, BC is 2 units
Since, hypotenuse is 10 units, Option a is not correct answer.
Option b: AC is 7 units, BC is 3 units
Since, hypotenuse is 10 units, Option b is not correct answer.
Option c: Angle B is 50 degrees, BC is 4 units
Since, hypotenuse is 10 units, Option c is not correct answer.
Option d: Angle A is 30 degrees, BC is 5 units
Since, hypotenuse is 10 units, Option d is the correct answer.
Option e: AC is 8 units, BC is 6 units
Since, hypotenuse is 10 units, Option e is the correct answer.
Thus, Option d and e are the correct answers.
