Answer:
parallel
Step-by-step explanation:
- y=-3/5x slope = -3/5
- y=5/3x slope = 5/3
- PARALLEL LINES have the SAME SLOPE
- PERPENDICULAR LINES have NEGATIVE RECIPROCAL SLOPE
Answer: 30, 60, 90 triangle ==> Option 3
Step-by-step explanation:
Lets say Angle A is the angle opposing the line of a triangle that has the length of 6. Lets say Angle B is the angle opposing the line of the same triangle that has the length of 
.
sin A=6/12=1/2
sin A=30 degrees.
sin B=
=
sin B=60 degrees.
Hence, triangle is 30, 60, 90 triangle ==> Option 3
To show the sides are equal all you need to do is draw the given Pentagon.. When angles are similar so are their opposite sides so chose any equal angle and dash the side of the Pentagon that's on the other side of the angle (dash =congruence)
It’s basically a 100% chance that the oceans will disappear in a few billion years, but according to some sources, most sealife (95%+) may be wiped out by the year 2100.
Answer:
32cm and 28cm
Step-by-step explanation:
Area of a trapezium=0.5 ( sum of parallel sides ) × height
600=0.5( 4+a+a)×20
where a is the length of the shorter side
600÷0.5=(4+2a)×20
1200=(4+2a)×20
1200÷20=4+2a
60=4+2a
60-4=2a
56=2a
56÷2=a
28=a.
since the longer side is 4 cm more than th shorter side , 28 +4=32
