The value of ∠X = 58.11°, If ΔWXY, the measure of ∠Y=90°, XW = 53, YX = 28, and WY = 45.
Step-by-step explanation:
The given is,
In ΔWXY, ∠Y=90°
XW = 53
YX = 28
WY = 45
Step:1
Ref the attachment,
Given triangle XWY is right angled triangle.
Trigonometric ratio's,
∅
For the given attachment, the trigonometric ratio becomes,
∅
.....................................(1)
Let, ∠X = ∅
Where, XY = 28
XW = 53
Equation (1) becomes,
∅ 
∅ = 0.5283
∅ =
(0.5283)
∅ = 58.109°
Result:
The value of ∠X = 58.11°, If ΔWXY, the measure of ∠Y=90°, XW = 53, YX = 28, and WY = 45.

Hello,
1) Verify if it is a 2 degree.
2) y=ax²+bx+c
Calulate a,b,c by Gauss's methode
a=3, b=0,c=-1
y=3x²-1
Answer:
89
Step-by-step explanation:
Given that the class has 28 students has 7 juniors and 21 seniors
mean score of the juniors = 73
Therefore, total score of junior = 73 × 7
= 511
mean score of seniors = y
Total score of seniors = 21y
Total score of the class = 511 + 21y
Mean score of the class = 85
Total score of the class = 85 × 28
= 2380
therefore,
511 + 21y = 2380
21y = 2380 -511
21y = 1869
y = 1869/21
y = 89
