Answer:
1.625 hours
Step-by-step explanation:
The equation is
d = rt where d is distance r is rate and t is time
65 = 40 *t
Divide each side by 40
65/40 = t
1.625 hours = time
Answer:
-10
Step-by-step explanation:
divide both sides by -4
simplify to v+8=-2
subtract 8 from both sides
v=-10
The second one, and the two last should be the right answer,
Hope this helped:)
Sin < C = 63/65 so m < C = 75.75 degrees
and tan B = 16/63 so m <B = 14.25 degrees
m < C + m<B = 75.75 + 14.25 = 90 degrees
Therefore m < A = 180-90 = 90
therefore the triangle is right-angled.
