Answer:
7/3
1
1/2
undefined
Step-by-step explanation:
1/1 ÷ 3/7 = 7/3 because you multiply the 1st fraction by the reciprocal of the 2nd
1/1 = 1
1/2 = 1/2
1/0 = undefined; anything divided by zero is considered to be undefined
All sides and angles are congruent
The <u>correct answer</u> is:
D) <span>when the plane makes a narrow angle with the base.
Explanation:
If a cross section of a prism is taken <u>parallel</u> to the base, the cross section will be the <u>same shape</u> as the base. In this case, it will be a 9 sided polygon.
If a cross section of a prism is taken <u>perpendicular</u> to the base, the cross section will be a <u>rectangle</u>, no matter how many edges the cross section goes through.
The only way to get a cross section with more sides than the original figure is to take a slant cross section, or one with an angle other than 90</span>° or 180° to the base. This makes D our only option.
Answer:
Option C.
Step-by-step explanation:
It is given that,
According to SAS congruence property, two triangles are congruent if they have two congruent corresponding sides and their included angles are congruent.
Angle between
is
.
Angle between
is
.
So,
by SAS, if
Therefore, the correct option is C.
