Answer:
Step-by-step explanation:
14.
by pythagoras,s theorem
15.
first perpendicular=y(say)
and second perpendicular=z (say)
y²=9²+7²=81+49=130
z²=y²+5²=130+25=155
x²=z²+4²=155+16=171
x=√(171)
All you have to do is go around and answer questions and you get points I guess
Answer = –3/2
Use rise/run to find the gradient, while finding the difference between the two points.
Equation of slope:
y2 - y1 / x2 - x1
-1-2 / 3-1
–3/ 2
Slope = –3/2
Answer:
60
Step-by-step explanation:
you should divide 152.4 by 2.54
the result will be 60
