Step-by-step explanation:

\sin( \alpha )  =  \frac{opp}{hyp}  \\  \sin( \alpha )  =  \frac{9}{10}  \\  \alpha  =   { \sin }^{ - 1} ( \frac{9}{10} ) \\  \alpha  = 64.15 \\  \alpha  = 64

A pole that is 3.1 m tall casts a shadow that is 1.18 m long.At the same time , a nearby tower casts a shadow that is 35.75 m lo
Georgia [21]

Answer:

94 m

Step-by-step explanation:

Write a proportion:

3.1 / 1.18 = x / 35.75

Cross multiply and solve:

1.18x = 3.1 × 35.75

1.18x = 110.825

x ≈ 94

Rounded to the nearest meter, the height of the tower is approximately 94 meters.

-3(-x+4)=5+3(x+1) please help​
Lostsunrise [7]

Answer:

No solution.

Step-by-step explanation:

Step 1: Write equation

-3(-x + 4) = 5 + 3(x + 1)

Step 2: Solve for <em>x</em>

  1. Distribute: 3x - 12 = 5 + 3x + 3
  2. Combine like terms: 3x - 12 = 3x + 8
  3. Subtract 3x on both sides: -12 ≠ 8

Here, we see that <em>x</em> has to equal no solution. No value of <em>x</em> would make the equation true.

Salvador bought 3 pounds of oranges that cost x cents per pound, a cucumber for 59 cents, and 2 bananas for 35 cents. write an e
Natali5045456 [20]
Since x is the cost of the oranges per pound in cents, the total amount spent on oranges in cents is 3x. Then, you spent 59 cents on cucumbers and 35 cents on bananas. The total amount spent on all food is the sum of the individuals. 3x+59+35. Combine like terms to get 3x+94. This will give you your total in cents. If you need a total in dollars, you would just multiply that expression by 0.01.
