<em>∠5 = 118</em>
Step-by-step explanation:
If you look closely at this image, you can see that ∠6 and ∠5 together will be equal to line c.
A straight line is equal to 180 so if we do...
= 118.
<u>∠5 will be equal to 118.</u>
If we go even further, because vertical angles are congruent...
∠7 = 62
∠8 = 118

I hope that it's a clear solution.
Answer:
a) 4.5 inches
b) 2√5 is irrational
Step-by-step explanation:
It was given that the edge length of a cube-shaped box is 2√5 inches long.
To estimate the length of the edge to the nearest tenth of an inch, we change √5 to decimals to obtain:
When we round to the nearest tenth, we obtain 4.5
We cannot find its exact value because √5 is an irrational number.
The product of a rational and an irrational number is irrational.
