Answer:

22.07 ft & 9.32 ft

Step-by-step explanation:

by sines rule :

20/sin 65° = r/sin 90° = y/sin 25°

r = 20×sin 90°/sin 65° = 20/0.9063

= 22.07 ft

y = 20×sin 25°/sin 65° =

20× 0.4226/0.9063

= 9.32 ft

In the equation below, b and c represent the price per pound, in dollars, of beef and chicken, respectively, x weeks after july
Bumek [7]

Answer:

D

Step-by-step explanation:

Since 1 and c are supposed to be equal, I put 2.35+0.25x=1.75+0.4x and solved that for the x. I got 4. Then, since I want to find the price of the beef, I plugged the 4 in the equation of "b" and got 3.35.

I made many mistakes when solving so I restarted many times which is why it took so long to answer. Whew, I actually found the answer though!

If you want to help, mark me brainliest, I'm only 1 away from getting virtuoso! That would make my day, and hope I made yours.

Bye!

Four oranges cost a total of 90 cents. At this rate, what is the cost of 3 dozen oranges? Step by step will put brilliants
allsm [11]
Four oranges cost 90 cents, an orange costs 90/4 cents, which is around 22.5 cents. Multiply this by 36 to get the cost of 3 dozen oranges, so 22.5 times 36 is 810, 810 cents, or 8.10 dollars.

Question 7: Option 1:  x = 33.5°

Question 8: Option 3: x = 14.0°

Step-by-step explanation:

<u>Question 7:</u>

In the given figure, the value of perpendicular and hypotenuse is given, so we have to use any trigonometric ratio to find the value of angle as the given triangle is a right-angled triangle

So,

Perpendicular = P = 32

Hypotenuse = H = 58

So,

sin\ x = \frac{P}{H}\\sin\ x = \frac{32}{58}\\sin\ x = 0.5517\\x = sin^{-1} ( 0.5517)\\x =33.48

Rounding off to nearest tenth

x = 33.5°

<u>Question 8:</u>

In the given figure, the value of Base and Perpendicular is given, we will use tangent trigonometric ratio to find the value of x

So,

Perpendicular = P = 5

Base = B = 20

So,

tan\ x = \frac{P}{B}\\tan\ x = \frac{5}{20}\\tan\ x = 0.25\\x = tan^{-1} (0.25)\\x = 14.036

Rounding off to nearest tenth

x = 14.0°
