Hello!

Angles in a triangle sum up to 180°, so:
180° = 58° + 58° + m∠3
Combine and subtract:
180° = 116° + m∠3
64° = m∠3
Thus, the answer is D.
<u>Answer:</u>
There are infinite solutions to the system of equations given
<u>Solution:
</u>
The given equations given are,
------ (i)
---- (ii)
Now putting the value of (i) in (ii) we get,





So, there are <em>infinite solutions</em> to the system.
Answer:
140 in^3
Step-by-step explanation:
The volume formula can be written as ...
A = Bh
Marcia found B = 20 in^2, so we can use that in the formula, along with h = 7 in.
A = (20 in^2)(7 in)
A = 140 in^3
The volume of the box is 140 cubic inches.
