In ΔSTU, s = 6.1 cm, t = 3.2 cm and u=7.4 cm. Find the measure of ∠S to the nearest 10th of a degree.

GuDViN [60]

Answer:

m∠S = 54.1°

Step-by-step explanation:

Use the law of cosines

$s^{2} = t^{2} + u^{2} - 2utcos S\\6.1^{2} = 3.2^{2} + 7.4^{2} - 2(3.2)(7.4) cos S$

37.21 = 10.24 + 54.76 - 47.36 cos S

-27.79 = -47.36 cos S

.586782 = cos S

arccos .586782 = S

m∠S = 54.1°

Help Now <br> Find The Lateral Area Of The Prism

Zina [86]

Answer:

Lateral Area = 176 cm²

Step-by-step explanation:

The prism is a rectangular prism

Formula for Lateral Area of the rectangular prism = 2(l + b)*h

Where,

Length (l) = 4 cm

Breadth (b) = 4 cm

Height (h) = 11 cm

Plug in the values

Lateral Area = 2(4 + 4)*11

= 2(8)*11

= 16*11

= 176 cm²
