Answer:
C: 40 degrees
Step-by-step explanation:
50+2y+y+10=180
60+3y=180
3y=120
y=40
<h3>The length of legs of isosceles right triangle is 8.5 cm</h3>
<em><u>Solution:</u></em>
Given is a isosceles triangle
hypotenuse = 12 cm
In an isosceles right triangle, the legs have equal lengths
Let these sides be each "a" cm
By pythogoras theorem,

Thus the length of leg of isosceles right triangle is 8.5 cm
V is the 3D region enclosed by S.
div(F)= <span>∂(x)/∂x + ∂(y)/∂y + ∂(10)/∂z = 2
</span>
<span>∫ = ∫∫∫ [V] div(F) dV = 2 ∫∫∫ [V] dV
Using cylindrical coords, ( rcos(θ), y, rsin(θ) ), dV=rdrdθdy
∫ = 2 ∫∫∫ rdrdθdy, [r=0,1], [θ=0,2π], [y=0,7−rcos(θ)] = 14π (easily integrated)</span><span>
