The sum of interior angles of a triangle is 180 degrees. If we’re trying to find the triangles last angle on the right, we will subtract 180-60-50 which equals 70. The angle missing on the right side is 70 degrees. There are opposite angles in this shape so the other angle beside a would also be 70 degrees. Now we only have a left and you do the same thing with the sum of interior angles with that triangle. So you do 180-70-65 and you’re left with 45. Therefore, a is 45 degrees.

Answer:
Therefore,
The lengths of side a and b are,
Step-by-step explanation:
Given:
Shape is of triangular prism.
Length = a
Width = b
Height = h =10 mm
Also, b = 2a
Volume of the Triangular Prism = 40 mm³
To Find:
a = ?
b =?
Solution:
Shape is of triangular prism. GIVEN
We Know that,
Substituting the given values we get
But ,
Given
Substituting a we get
Therefore,
The lengths of side a and b are,
the question says that the total price equalled of the antiques is 70. It also says that she bought a table, which was 44, and 2 chairs (x). We can form this equation.
44 + 2x = 70. <------the 2x comes from 2 times the cost of one chair (x) and the . 44 comes from the cost of the table. The total is 70 dollars.
2x = 26 <-------solve algebraicelyy(sry about by spelling)
x = 13 <-------this is the cost of only one chair.
Answer: $13
