Answer:
<u>x = 90</u>
Step-by-step explanation:
We know based on the trigonometric identity that :
Here, it's given : tan (x - 45)° = 1
<u>Equating</u>
- tan 45 = tan (x - 45) [both are equal to 1]
- 45 = x - 45
- <u>x = 90</u>
Answer:
x = 111°
Step-by-step explanation:
We know that angles in a triangle add up to 180°
Step 1: Find angle supplementary to <em>x</em>
82 + 29 + x = 180
111 + x = 180
x = 69°
Step 2: Find angle <em>x</em>
Both the angles are supplementary, meaning they add up to 180°.
x + 69 = 180
x = 111°
To solve this, you must add 2/3 + 1/4 + 1/4.
First, convert them all to have common denominators.
2/3 x 4/4= 8/12
1/4 x 3/3= 3/12
1/4 x 3/3= 3/12
Now, add them...
8/12 + 3/12 + 3/12 = 14/12 gallons.
Now, since it's an improper fraction, first lets simplify...
14/12 divided by 2/2 = 7/6
Now, convert 7/6 into a mixed number...
7/6= 1 1/6
SO, Lila collected 1 and 1/16 of a gallon in all
I HOPED THIS HELPED! :D
4x + 2y = 56. 5x + y = 34. y = -5x + 34. 4x + 2(-5x + 34) =56. 4x -10x + 68 = 56. -6x = -12. x=2. 4(2) +2y = 56. 8+2y = 56. 2y = 48. y = 24.
x=2, y=24.

Answer:
"Eduardo did not use the correct formula for the circumference"
Step-by-step explanation:
The circumference formula is C = 2πr
Area formula is A=πr^2
Volume formula is correct. The steps area also correct to find r, the radius.
But in the end, he put the formula for circumference wrong. He used the formula for Area, NOT Circumference.
Hence, "Eduardo did not use the correct formula for the circumference" should be the correct choice for this question.
