Answer:
180
Step-by-step explanation:
Area of troiangle=180
A+B+C=180
22+90+B=90
112+B=180
B=180-112
B=68
perimeter=A+B+C
22+90+68=180
Answer:
~~12.413 units
Step-by-step explanation:
see attatchment
solve for x, or side 1
tangent= opposite side/adjacent side
tan of angle 22= x/5
tan(22)=x/5
5*tan(22)=x
solve for y, or side 2
cosine= adjacent side/hypotenuse
cos of angle 22= 5/y
cos(22)=5/y
y*cos(22)=5
y=5/cos(22)
put into calculator
side 1 length , side 2 length, hypotenuse length (given)
5*tan(22), 5/cos(22), 5
5*tan(22)+ 5/cos(22)+ 5
~~12.413
hope this helps.
