divide distance by time
32 /1.25 = 25.6 miles per hour
Answer:
omg Thank u so much ur so nice
Step-by-step explanation:
A = 37 degrees ; B = 82 degrees
the angle A plus 143 must measure 180 degrees
angle A = 180 - 143 = 37 degrees
the sum of the inner angles of a triangle is 180 degrees
A + B + C = 180
37 + B + 61 = 180
B = 180 - 98 = 82 degrees
.87 I think
I believe you have to evaluate the inverse tangent first then do the sine.
tan^-1 34/19 is about 1.06
sin 1.06 is about .87
