Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.Step-by-step explanation: ratios
Answer:
a) 23
Step-by-step explanation:
Answer:
23.6
Step-by-step explanation:
<u><em>Finding AC:</em></u>
Cos 61 = 
0.48 × 10 = Adjacent
AC = 4.8
<u><em>Now, CB:</em></u>
Cos 29 =
0.87 × 10 = CB
CB = 8.8
<u><em>The perimeter:</em></u>
=> 10+4.8+8.8
=> 23.6
Wouldn't all the angles equal 180? We've been trying to learn these but I think so. Subtract both numbers by 180 and it should be the answer. Sorry if it's wrong but I'm not sure. I kinda hope this helps you any
