I think your teacher may have made a typo. Refer to the diagram below. If we ignore segment ZA for now, we can see a rectangle forms with angle W = angle Y = 90. Also, we can see that WX = 6 is the horizontal base and WZ = 8 is the vertical height.
However, the side opposite WZ (which is XY) should also be 8 cm tall, and not 6 cm. If XY was 6 cm, then point Y would move to where point A is located (and the quadrilateral would be WXAZ instead of WXYZ). This new quadrilateral would not have a 90 degree angle at point Y's new location.
In other words, if we want angle Y to be 90 degrees, then side XY must be 8 units long. I have a feeling this is where the typo is, but your teacher might have been intending to say something else.
The answer should be 18 because 10/1 1/4=0.125+1 1/4=1.375+0.125=1.5x12=18
this should be correct i’m truly sorry if it’s not
Answer : 15
We know these triangles are congruent. To find the missing side, you first have to find out what the scale factor is. To do this you can just divide side QS by side AC, which would give you 2.5.
You would then multiply this scale factor by side BC, giving you side N, which is 15.
6x=120-5y -> x=20-5/6*y -> 7(20-5/6*y) + 11y =202 -> 140-35/6*y + 11y = 202 -> 140+31/6*y=202 -> 31/6*y = 62 -> y = 12.
Answer:
To find the angle RST we have to first find SRT As the exterior angle adjoined with SRT =53°
so the SRT = Outer angle adjoined with angle SRT
angle SRT = 53° [°.° vertically opposite angles are equal]
Angle SRT + Angle STR + Angle RST = 180°
=>53° + 75° + Angle RST =180°
=> 128° + Angle RST = 180°
=> Angle RST =(180-128)°
= 52°
SO NO. <em><u>C</u></em> IS correct what Cate says is absolutely right
