Answer:
7.6
Step-by-step explanation:
m<DBA is 68 degrees
Area = b*h and in some cases * 2 so you need to do this, 64*52 + 40*28= 4448 yd2
Answer: y=-3x+29
Step-by-step explanation:
First put in y-intercept form to find the slope

Slope of the 1st equation is 1/3- the slope of the line perpendicular is the opposite reciprocal, so in the case it is -3
Use the point and the new slope to write the new equation in point slope format

Parallel because they have the same slope. Y+4= -1/2(x-2) is in point slope form, simplified to y intercept form is y=1/2-5... The slope (m) in both equations is the same, if you graphed the equations they would be parallel
