Answer:
second
Step-by-step explanation:
substitute y=6 and x=1 in the given relations and see if works
y=2x will be 6 = 2*1 false
y=x+5 will be 6 = 1+5 true
because this is true check all the other y and x and if all true is good
7=2+5 true, 8=3+5 true 9= 4+5 true, 10=5+5 true, so second is good
y=2x+1 will be 6=2*1+1 false
y=3x+1 will be 6=3*1+1 false
Answer:
m∠B = 66.3°
a = 0.0319
b = 0.0726
Step-by-step explanation:
Sum of the interior angles of a triangle = 180°
⇒ m∠A + m∠B + m∠C = 180°
⇒ 23.7 + m∠B + 90 = 180
⇒ m∠B = 180 - 90 - 23.7 = 66.3°
We can use the sine rule to help solve the missing side lengths.
<u>Sine rule</u>
where A, B and C are the angles and a, b and c are the side lengths opposite the angles.
Therefore,
