Answer:

x = 8

Step-by-step explanation:

Using the sine or cosine ratio in the right triangle and the exact value

sin30° = \frac{1}{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{4}{x} = \frac{1}{2} ( cross- multiply )

x = 8

Find the value of x, y, and z.
egoroff_w [7]

Answer:

x = 61°

y = 61°

z = 58°

Step-by-step explanation:

In the given triangle, measures of two sides are equal. So, measures of angles opposite to them are also equal.

Therefore,

x + x + 58 \degree = 180 \degree \\  \\ 2x = 180 \degree - 58 \degree \\  \\ 2x = 122 \degree \\  \\ x =  \frac{122 \degree}{2}  \\  \\ x = 61\degree  \\  \\ y = 61\degree  \\  ( \angle s \: in \: the \: alternate \: segment) \\ \\ z = 58\degree  \\  ( \angle s \: in \: the \: alternate \: segment) \\

Sierra goes shopping and finds a jacket on sale for $120. The original price was $150. What was the percent change in the price
enot [183]
The sale price of the jacket that Sierra wants to buy = $120
Actual price of the jacket that Sierra wants to buy = $150
Amount of sale given on the jacket that Sierra wants to buy = (150 - 120) dollars
                                                                                                = 30 dollars
Percentage change in the price of jacket = (30/150) * 100
                                                                   = (1/5) * 100
                                                                   = 20 percent
So the percentage change in the price of the jacket that Sierra wanted to buy was 20%. The correct option among all the options given in the question is option "C".I hope that the procedure is clear enough for you to understand.
