Answer:
original number is 57
Step-by-step explanation:
I am not sure if there is a correct way to do this...but I am just guessing and checking to find the answer.
the possible 2 digit numbers that equal 12 are :
39,93,48,84,57,75,66
the number obtained by interchanging the digits exceeds the original number by 18....so the original number is 18 less then the new number.
the only two numbers whos difference is 18 is 57 and 75.....75 - 57 = 18
so the original number is 57.....and the new number obtained by interchanging the digits (75) exceeds the original number by 18...and 75 - 57 = 18.
Answer:
2.64cm
Step-by-step explanation:
A = π r^2
5.5 = π r^2
1.75 = r^2
r = 1.32
Diameter is then 2(1.32) = 2.64
We know: the sum of the angles measures in a triangle is 180°.
Therefore we have the equation:
64° + 75° + α = 180°
139° + α = 180° <em> subtract 139° from both sides</em>
α = 41°
α and ∠2 are Supplementary Angles - they add up to 180°.
α + m∠2 = 180°
41° + m∠2 = 180° <em>subtract 41° from both sides</em>
<h3>m∠2 = 139°</h3>
