Answer:
The number of hardback books in book sale = 58
Step-by-step explanation:
Let the number of hardback books = m
So, the number of paperback books = 3 ( number of Hardbacks) - 12
= 3 m - 12
⇒the number of paperback books = 3 m -12
Now, total number of paperback books = 162
⇒ (3m -12) = 162
or, 3m = 162 + 12
or, 3m = 174 ⇒ m = 174 / 3
or, m = 58
Hence, the number of hardback books = 58
A I’m Not Completely Sure But Same Things As Right Angles
Answer:
The answer is B.
Step-by-step explanation:
the angle is not even 90 degrees so anything bigger is an automatic no and it's pretty obvious that the answer is not 0. Lol
Answer:
45 degrees
Step-by-step explanation:
Think of it like this the sum of the angles in a triangle are the always the same 180 degrees.
So now, we do 180 - 90 = 90 this is the sum of the other angles.
We shall assume that they are the same and divide 90/2 = 45 degrees each
Ok here are some things to understand while solving!
- If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.
- If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
- If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
- If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
- If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.
- Without knowing at least one side, we can't be sure if two triangles are congruent. (which we do!)
Hope this helped!

Answer:
Ratio of Able's score to Ben=6:1
Ratio of Ben's score to Cal's=1:2
Ratio of able's score to ben;s score to cal's score=6:1:2
Step-by-step explanation:
Let Ben's score =x
Able scored six times Ben's score
Able=6*x
=6x
Cal scored a third of Able's score
Cal=1/3 of 6x
=1/3(6x)
Ratio of Able's score to Ben
6x:x
=6:1
Ratio of Ben's score to Cal's score
x:1/3(6x)
=x:6x/3
=x:2x
=1:2
Ratio of able's score to ben;s score to cal's score=6:1:2
