I think that’s the answer
29°
triangles can only have 180°
This is a right triangle, so one angle is 90°, leaving us with 90° left
90°-61°= 29°
Answer: a. -3/5
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
Since the triangle is right we can use the cosine ratio to find IR
cos60° =
=
= 
Cross- multiply
IR = 14 × cos60° = 14 × 0.5 = 7
