Answer:
58°
Step-by-step explanation:
<u>Start with the equation</u> 2x + 2 + 90 = 148
<em>( I got the 90 from Angle B since it is a right angle.)</em>
<u>Combine like terms</u> 2x + 92 = 148
<em>( 90 and 2 didn't have variables so you could add them together.)</em>
<u>Subtract 92 from both sides</u> 2x + 92 = 148
-92 -92
<em>(The opposite of addition is subtraction.)</em>
<u>Now write out the new equation</u> 2x = 56
<u>Divide both sides by 2</u> =
<u>You'll end up with...</u> x = 28
<u>To find the measure of angle BAC, plug in 28 where the x value is</u> 2(28) + 2
<u>This gives you the answer</u> 58°
*Given
3(x+y)=y
y is not equal to zero
*Solution
1. The given equation is 3(x+y) = y and we are tasked to find the ratio between x and y. Distributing 3 to the terms in the parenthesis,
3(x+y) = y
3x + 3y = y
Transposing 3y to the right side OR subtracting 3y from both the left-hand side and the right-hand side of the equation would give
3x = -2y
Dividing both sides of the equation by 3,
x = (-2/3)y
Dividing both sides of the equation by y,
x/y = -2/3
Therefore, the ratio x/y has a value of -2/3 provided that y is not equal to zero.
Answer:
12.67 minutes
Step-by-step explanation:
Time taken is given by distance divided by speed
Given distance of 228, 000, 000 km and speed of light as 300, 000 km/s then time will be
Time=228, 000, 000/300, 000=760 seconds
Conversion
60 seconds make up 1 minute
760 seconds will be 760/60
Time=760/60=12.666666666666
Rounded off, this is 12.67 minutes
