Answer:

\boxed{\dfrac{34}{15}}

Step-by-step explanation:

\text{Use }\LaTeX (ノ◕ヮ◕)ノ*:・゚✧

\dfrac{8}{5} - - \left(\dfrac{2}{3}\right)

\dfrac{8}{5} - \left[-\dfrac{2}{3}\right]

\dfrac{8}{5} +\dfrac{2}{3}

\dfrac{8(3)}{5(3)} +\dfrac{2(5)}{3(5)}

\dfrac{24}{15} +\dfrac{10}{15}

\boxed{\dfrac{34}{15}}

In TUV below, find m T to the nearest degree
Andre45 [30]

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
