Answer:
24.84
Step-by-step explanation:
12.15 + 3.75 = 15.90
15.90 + 8.94 = 24.84
If you divid 8.4 x 107 and 3 x 103 you should get 2.8 x 104
Answer:
w
Step-by-step explanation:
Answer:
T = 88 degrees to the nearest degree
Step-by-step explanation:
To find the measure of the angle T, we can use the cosine rule
We have the formula as;
t^2 = u^2 + v^2 - 2uv Cos T
t = 8.1
u = 7.1
v = 4.2
8.1^2 = 7.1^2 + 4.2^2 - 2(7.1)(4.2) cos T
-2.44 = -59.64 cos T
cos T = (2.44)/(59.64)
T = arc cos (2.44/59.64)
T = 87.66
to the nearest degree, this is 88 degrees
