Answer:
60 degrees
Step-by-step explanation:
Similar shapes have the same angles but different side lengths.
Cos(A) will be 3/5 Cos(A) is adjacent/hypotenuse. So here we have sin(A)=opp/hyp which is 4/5 and tan(A)=opp/adj which is 4/3. So cos(A) is adj./hyp and knowing the previous 2 terms of sin(A) and cos(A), you can go ahead and find Cos(A). So cos(A) is 3/5
Triangle
1+1+5=7
7×4=28
28÷2=12
rectangle
12×5=60
whole shape
60+12=72in squared
