We can see that both triangles are right angle triangle as per information given into picture. So we will prove that they are similar then use properties of similar triangle to find the value of d.
In triangle STV and triangle XWV:
∠STV = ∠XWV { both are equal to 90 degree}
∠TVS = ∠WVX { vertically opposite angles are equal}
Hence by AA (Angle Angle) similarity postulate of the triangles, It is proved that triangle STV and triangle XWV are similar.
We know that ratio of corresponding sides of similar triangles are equal so we can write:


350*180=400d
63000=400d
divide both side by 400
157.5=d
Hence final answer is d=157.5 m.
Answer:
A = 84 
Step-by-step explanation:
To find the area of a trapezoid, use this equation:

a = top base
b = bottom base
h = height
Let's classify all the sides:
a = 4 ft
b = 10 ft
h = 12 ft
Now, let's plug all these into the equation:

Add what's in the numerator
Divide 14 by 2
A = 84
Multiply 7 by 12
So, the area of the trapezoid is 84
.
Hope this helps!!
A right triangle means that one angle is 90 degrees. If the other is 30 then we can figure out the last one.
A triangle’s interior angles add up to 180 so all we have to do is subtract the other angles from 180 to find the remaining one.
180-90-30=60.
The third angle is 60 degrees.
