<t =33 since triangle RUT is isosceles (RU = TU)
<r + <u + <t = 180 triangle = 180
33 + <u + 33 = 180
66 + <u = 180
< u =114
<rus = < sut from the diagram
<rus + <sut = <u
x + x = 114
2x = 114
divide by 2
x = 57
That would be b
hope this helps
{ 3x-2y=2
{ y=2x+8
{ -2y=2-3x
{ y=2x+8
{ y= -1+3/2x
{ y= 2x+8
-1+3/2x = 2x+8
x=-18
y= 2(-18)+8
y= -28
(x,y) = ( -18,-28)

Solution check
{ 3(-18)-2(-28)=2
{ -28=2(-18)+8
{ 2=2
{ -28=-28
Answer:
About 158 times
Step-by-step explanation:
Represent the rate of human heart with H and sparrow's heart with S
Required
Determine how many times faster is S than H
To do this, we simply divide S by H i.e.
--- approximated
<em>Hence, the sparrow's heart beats about 158 times faster than the human hearts</em>
