Answer:
" There are 23 people in the club."
Step-by-step explanation:
We want to know how many member's friends came to the meeting.
We know that:
There are 23 people in the club
5 members of the club, invited 2 friends each.
So we have 5 times 2 friends invited:
Then there are 5*2 = 10 people invited to the first meeting.
Notice that the fact that there are 23 people in the club is never used, them the information that is not necessary to solve this problem is " There are 23 people in the club."
Answer:
<h2>D. 18</h2>
Step-by-step explanation:
We know:
1. Diagonals of a rhombus are perpendicular.
2. Diagonals divide the rhombus on four congruent right triangles.
3. The sum of measures of acute angles in a right triangle is equal 90°.
Angles CAD and ACB are alternate angles. Therefore they are congruent:
m∠DAC = m∠ACB ⇒ m∠ACB = x°.
From 3. we have the equation:
(5x - 18) + x = 90
(5x + x) - 18 = 90 <em>add 18 to both sides</em>
6x = 108 <em>divide both sides by 6</em>
x = 18
Some shapes that are classified as quadrilaterals are square, rectangle, ... It has 4 right angles and the opposite sides are equal. ... A parallelogram has both pairs of opposite sides that are parallel. ... It has exactly one pair of parallel sides.
