Answer:
A x-198,y-99
Step-by-step explanation:
since sin p/h you can say
perpendicular is 99
and hypotenuse is x
sin 30=99/x
x=198
and cos is b/h
base is y
and hypotenuse is x
cos 30=y/198
y-99
We can calculate the length of pq=√(2-3)²+(-1-1)²+(0+1)²=√6
pr=√(2-0)²+(-1-1)²+(0-2)²= 2√3 and qr=√18= 3√2
Now we have cosinqpr= (6+12-18):(2.√6.2√3)=0 or this triangle is right at p
And the area is 1/2 x √6 x 2√3= 3√2
Answer= 53
the square equal are 90 angles
a straight line equals 180.
90+37=127
180-127=53
