Find each measurement indicated round your answers to the nearest tenth. Part 1d. NO LINKS OR ANSWERING QUESTIONS YOU DON'T KNOW!!! ​

see explanation

Step-by-step explanation:

Using the Sine rule in all 3 questions

(1)

= , substitute values , firstly calculating ∠ B

[ ∠ B = 180° - (78 + 49)° = 180° - 127° = 53° ]

= ( cross- multiply )

a sin53° = 18 sin78° ( divide both sides by sin53° )

a = ≈ 22.0 ( to the nearest tenth )

(3)

= , substitute values

= ( cross- multiply )

45 sinC = 35 sin134° ( divide both sides by 35 )

sinC = , then

∠ C = ( ) ≈ 34.0° ( to the nearest tenth )

(5)

Calculate the measure of ∠ B

∠ B = 180° - (38 + 92)° = 180° - 130° = 50°

= , substitute values

= ( cross- multiply )

BC sin50° = 10 sin38° ( divide both sides by sin50° )

BC = ≈ 8.0 ( to the nearest tenth )

how is that middle school

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
