Sin(x) =9/25
Sin(x)=0.36
Sin^-1 (0.36)= 21.10
x=21.10
Answer:
x=17
Step-by-step explanation:
It's a right angle, therefore it has to equal 90.
90=22+4x
90-22=68
68 divided by 4 is 17

30 30 30 30 30 30 30 30 30 30 30 30 xD
D because d is always right hahahahaha
Adding them up, we have 1/2+3/20+2/5+4/5. We can do a bit of guess and checking to see that 2, 5, and 20 go into 20. 20/2=10 and 20/5=4, so we multiply 1/2 by 10/10 and 2/5 and 4/5 by 4/4 to get 10/20+3/20+8/20+16/20= 37/20
