Answer:
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.
If the decimal is 1 number divide that number into 10 Then simplify the fraction if possible. if the decimal are 2 numbers divide those 2 numbers by 100 Then simplify the fraction if possible
3 numbers:by 1000, etc
Ex 0.4= 4/10 = 2/5
Answer:
C
Step-by-step explanation:
The parallel lines create similar triangles. Which means sides are proportional...


So if then the ratio of AR to AS = 5/7
Create a proportion with the other similar triangle that contains the shared side:

Cross multiply
e =
