Answer:
C. ⅐
Step-by-step explanation:
Recall: the slope of a line that is perpendicular to another is the negative reciprocal of the slope of the other line that it is perpendicular to.
Thus:
Slope of red line = -7
The green line that is perpendicular to the red line will have a slope that is the negative reciprocal of -7.
Negative reciprocal of -7 = ⅐
The slope of the green line is therefore ⅐
Answer: y= x/5 -6
Step-by-step explanation: gradient= 1/5...(m1m2=-1)
y-y1=M(x-x1)
y-8=1/5(x-10)
5y-40=x-10
y=x/5-6
Answer:
6.32455532034 or just 6
Step-by-step explanation:
A square is basically two triangles put together and since a square has four right angles you can use the Pythagorean Theorem to do this.
A squared +b squared <24
5 squared x 5 squared = 25
Sooooooo...... ;)

Answer:
area of rectangle : 180 sq ft
area of triangle : 30 sq ft
area of entire composite figure : 210 sq. ft
Step-by-step explanation:
rectangle : 15*12= 180
triangle : 15*4=60 /2 = 30
entire : 180 + 30 = 210
