  3. Multiplication
  4. Division
  5. Addition
  6. Subtraction

First equation:

12 + (38 - 18)2 = 12 + 20 × 2 = 52

Second equation:

(12)2 - 6(2 - 23) = 24 - 6(-21) = 24 + 126 = 150

In ΔSTU, u = 23 inches, ∠T=158° and ∠U=17°. Find the length of t, to the nearest 10th of an inch.
Evgesh-ka [11]

Answer: t = 29.5 inches

Step-by-step explanation:

Given that the ΔSTU, u = 23 inches, ∠T=158° and ∠U=17°. 

We can Find the length of t by using sine rule

t/saint = u/sinU

t/sin158 = 23/sin17

t = sin158 × 23/sin17

t = 29.47 inches

t = 29.5 inches
