Answer:
∠ R 90°
Step-by-step explanation:
Given that in triangle RST
Now as per condition one angle is greater than sum of other two angles.
Since in triangle ,sum of all three angles = 180°
Hence if one angle is 90° then sum of other two must be equal to 90°
And if one angle is 90° then only other two angle be 45° each
Here Let if angle s = angle T = 30° then with this condition angle r is 120° , which is greater than 90°
So, from above it conclude that
For ,
∵ ∠ R = 120° , then it is greater than 90°
I.e , ∠ R 90°
Answer
Answer:
(2, -4) would be point b.
Step-by-step explanation:
This is because -2 was on the negative side of the x axis before the refection and now it's on the positive side of the x axis
Answer:
B
Step-by-step explanation:
Mean is the average so add the numbers and divide by 9.
Mean = 25
Volume = (LWH)/2
Length = Difference between the two x values
Using A (4, 3, 1) an B (0, 3, 1) we can use these two x values to find the length of the triangular prism
4 - 0 = 4
Length = 4
Width = This is exactly the same process, however we use the y values
Using E (4, 0, 1) and A (4, 3, 1) we can use the two y values to find the width
3 - 0 = 3
Width = 3
Height = Again, the same but using the z values
Using E (4, 0, 1) and D (4, 0, 5) we can find the difference
5 - 1 = 4
Height = 4
Now we have all out values, we can put them in the formula to work out the volume.
(4 x 3 x 4)/2
48/2
24 (units)³
