Answer:
2
Step-by-step explanation:
The root of every order of 1 is still 1, in other words, we have
So, if we evaluate the function at 1, we have
Answer:
(a) PT = 13 cm
(b) <PTR =
Step-by-step explanation:
(a) Applying the Pythagoras theorem to QST, we have;
= +
= +
= 36 + 64
100
QS =
= 10
QS = 10 cm
Since QS = TR, then;
WT = TR
= x 10
WT = 5 cm
Thus, applying Pathagoras theorem to PWT;
= +
= +
= 144 + 25
= 169
PT =
= 13
PT = 13 cm
(b) To determine <PTR, TR = 10 cm. Apply the required trigonometric function;
Cos θ =
Cos θ =
= 0.7692
θ = 0.7692
= 39.7179
θ =
Therefore, <PTR =
