Use arccos...cos^-1 so
cos^-1 (0.8195)
it equals 34.96522689°
first, we can find the slope from the equation that is given buy solving the equation for y
3x+2y = 6
2y = 6-3x
y = 3-3/2x
y = -3/2x+3
now that the equation is in slope-intercept form, we can easily see that the slope of the given line is -3/2
perpendicular lines have slopes that are negative reciprocals, so we can just take the negative reciprocal of the slope we have
-3/2 → 3/2 → 2/3
the slope of the perpendicular line is 2/3

If you have covered function tranformations
is an exponential function, likely something like
but shifted upwards by 3 units and with a coefficient multiplying "x" something like "2"
so... try graphing in your calculator
To find the area of a rectangle, we must use the formula, A = lw, where the variable l represents the length of the rectangle and the variable w represents the width of the rectangle. To find the area, we just have to substitute in the values we are given for the length and width (shown in the picture above) to calculate the area. This is modeled below:
A = lw
A = 12 cm * 5 cm
To solve, we simply multiply the two factors on the right side of the equation to find the area. Remember that because we are multiplying these two numbers together, we should end up with an answer that has squared units!
A = 60 cm²
Therefore, your answer is that the area of the rectangle is 60 cm².
Hope this helps!
