Answer:
1.) 9.32
2.) 4.82
Step-by-step explanation:
neat trick i learned that really helps: SOH-CAH-TOA
Sine (opposite, hypotenuse), Cosine (Adjacent, Hypotenuse), Tangent (Opposite, Adjacent)
1.)
sin(21) = x/26 <----------- multiply by 26 to get x by itself
26*sin(21) = x <----------- multiply 26 by sin(21)
9.32 = x <------ rounded answer
2.)
cos(64) = x/11 <------------ multiply by 11 to get x by itself
11*cos(64) = x <---------------- multiply 11 by cos(64)
4.82 = x <-------- rounded answer
