Answer: x = 36.08
Step-by-step explanation: We can use <u>Law</u> <u>of</u> <u>Sines</u> to determine x, which is written as:
where
F is the angle at vertex F
The angle is calculated knowing that the sum of all internal angles of a triangle is 180°:
F + 49 + 90 = 180
F + 139 = 180
F = 180 - 139
F = 41
Then, Law of Sines will be:
Sin(90) = 1
sin (41) = 0.6560
Substituing and rearraging:
x = 36.08
<u>The value of x is 36.08 units</u>
Answer:
x = 0.59 to the nearest hundredth
Step-by-step explanation:
Look at the attached figure
- The equation is 2x + = 3
- The red curve represents the left side of the equation
- The blue line represents the right side of the equation
- The solution of the equation is the point of intersection of the two graphs
∵ There are 5 small squares between every 2 numbers on the x-axis
∴ Each square represents 0.2
∵ There are 5 small squares between every 2 numbers on the y-axis
∴ Each square represents 0.2
∵ The point of intersection between the 2 graphs is nearest to
the 3rd small square after the zero on the x-axis
∵ 0.2 × 3 = 0.6
∴ The x-coordinate of the point is approximately located at 0.59
∴ x = 0.59 to the nearest hundredth
Answer:
1000
Step-by-step explanation:
Question
is -3 a solution of
-3x+5=5x-25
Answer:
<h2>
No, the solution is -15/4</h2>
Step-by-step explanation:
-3x + 5 = 5x - 25
-8x = -30
x = - 30 : 8
x = - 15/4
