Answer:

m<T = 28^{o}, m<M = 62^{o} and m<Z = 90^{o}

Step-by-step explanation:

From the given ∆TMZ, let the measure angle T be represented by T.

So that,

m<M = 2T + 6°

m<Z = 5T - 50°

Sum of angles in a triangle = 180^{o}

T + (2T + 6°) + (5T - 50°) = 180^{o}

8T -44^{o} = 180^{o}

8T = 180^{o} + 44^{o}

    = 224^{o}

T = \frac{224^{o} }{8}

   = 28^{o}

Therefore,

i. m<T = 28^{o}

ii. m<M = 2T + 6°

        = 2 x 28^{o} + 6°

        = 62^{o}

m<M = 62^{o}

iii. m<Z = 5T - 50°

            = 5 x 28^{o} - 50°

            = 140^{o} - 50°

            = 90^{o}

m<Z = 90^{o}

The formula for simple interest is

You can either substitute the given values first and the solve for

T, or you can transpose the formula to have

T as the subject.

T=100xSIPR

T=100 x 637.50

T=100×637.502500×17

T=1.5

As time is always in years, this means it was for

112 years which is 1 year and 5

months
