Answer:
it's c, 80 degrees
Step-by-step explanation:
a triangle is like a straight line, but it has 3 different angles that all add up to 180 degrees
Step-by-step explanation:
the x distance from A to B is 3 (from -1 to 2), and the y distance is 15 (from -4 to 11).
the x distance from C to D is also 3 (from 1 to 4), but the y distance is 9 (from 1 to 10).
so, the slopes are different
AB : 15/3 = 5
CD : 9/3 = 3
and the lines are therefore not parallel.
perpendicular slopes are simply inverting y and x in the ratio and flip the sign (from - to + and vice versa). but that is not the case here either (just to start - both slopes are positive).
so, the 2 lines are "neither".
<span>The proportion of clay uses is 3/8 (Three Eighths). That is 3 lbs. of clay to every 8 vases. This is determined by the first given proportion 3 lbs./8 vases and confirmed by the second. To prove that is the case you divide the second ration by the first numerator:
9 divided by 3 = 3 and 24 divided by 3 = 8. So the proportion for 9/24 is still 3/8. This can also be used to increase the number of vases made. For example if 40 vases need to be made:
we divide 40 by the numerator 8 = 5. So we need 5 portions of 3 to make 40 vases. 5 times 3 = 15. So the 15 lbs. of clay is needed for 40 vases.</span>
Answer:
Step-by-step explanation:
use the Pythagorean theorem to find the length of the third sides.
c²=a²+b²
c²=7²+3²
=49+9
=58
so, c²=√58
area of the square is 58 units
