Answer:
You need to use sohcahtoa to find your answer.
first you gotta identify what sides of the triangle you have.
You're missing the hypotenuse, and you have the value of the adjacent.
since you have the adjacent and need the hypotenuse, you're going to use cosine to find x
cos(65) = 16/x
x = 37.859
Both of these problems will be solved in a similar way, but with different numbers. First, we set up an equation with the values given. Then, we solve. Lastly, we plug into the original expressions to solve for the angles.
[23] ABD = 42°, DBC = 35°
(4x - 2) + (3x + 2) = 77°
4x+ 3x + 2 - 2 = 77°
4x+ 3x= 77°
7x= 77°
x= 11°
-
ABD = (4x - 2) = (4(11°) - 2) = 44° - 2 = 42°
DBC = (3x + 2) = (3(11°) + 2) = 33° + 2 = 35°
[24] ABD = 62°, DBC = 78°
(4x - 8) + (4x + 8) = 140°
4x + 4x + 8 - 8 = 140°
4x + 4x = 140°
8x = 140°
8x = 140°
x = 17.5°
-
ABD = (4x - 8) = (4(17.5°) - 8) = 70° - 8° = 62°
DBC =(4x + 8) = (4(17.5°) + 8) = 70° + 8° = 78°
Answer:
Step-by-step explanation:
tan Ф = opposite side divided by the adjacent side
tan Ф = opp/adj in your problem Ф is x
tan x = 4/9
x = arctan (4/9) on your calculator arctan is might look like inverse tan
or you might have to use the 2nd (second) button and then tan
x = inverse tan (0.44444 repeating) try it on your own calculator
= 23.962488974578183 rounds up to 24.0
= 24.0
Answer:
Follows are the solution to this question:
Step-by-step explanation:
Following are the step which is used in the question:
- Step 1, In this use the sheet on the formulas tab we use the function, that is the part of the FLG "Function Library group".
- Step 2, In this step, click the Financial button, and after that click on the PMT.
- Step 3, after clicking on PMT apply or Enter the value that is "B3/12", in this it provides the rate argument box.
- Step 4, after insert value in B4, it provides the Naper argument box, that input the value in "B2" cell into the Pv argument box.
- Step 5, After click the OK button.
To solve this answer, you are trying to find 55% of 600, because that is the number of people who chose plastic bag.
55% can be re-written as 55/100 OR 0.55 since percentages are always out of 100.
So, we do 0.55*600, which gives us 330. 330 people carry plastic bags.
