Hello!
To discern whether or not triangles are congruent, you should try using the Pythagorean Theorem (a²+b²=c², where a and b are legs, and c is the hypotenuse) to make sure that all the sides have an equal length. Then find the area just to verify that they are congruent (A=1/2bh).
We can use these to find whether two triangles using SAS (side angle side) postulate. If the lengths of two sides of a triangle and the angle of their connecting angle (ideally named) match up with the measurements of a side, angle, and side of another triangle, they are congruent.
I hope this helps!
Answer:
Step-by-step explanation:
1,-18
First you need to find a common denominator. 11/15 = 22/30
3/10= 9/30
9/30+22/30= 1 1/30
Hope this helps!
Answer:
the answer is 30/99, which simplifys to 10/33
Step-by-step explanation:
Hope this helps. You always change the denomiter to 99 for repeating decimal. Good luck
Answer:
square foot per hour
Step-by-step explanation:
The total area covered = 34 square foot
Time taken = 12 hours
This implies that it takes 12 hours to cover 34 square foot.
Using proportionality,
12 hours ---------------------------------------> 34 square foot
Dividing both sides by 12
---------------------------> 
1 hour ---------------------------------------> square foot per hour
The unit rate in square feet per hour is square foot per hour
