Answer:
101.76
Step-by-step explanation:
(12.9−3.1)(6.2)−2+43
=(9.8)(6.2)−2+43
=60.76−2+43
=58.76+43
=101.76
Answer:
2. I am pretty sure that it is right angles are congruent.
4. Angle O and R are congruent, never heard of their angles theorem but I think it might be related to CPCTC.
Step-by-step explanation:
Well a square is always used to represent a right angle so and both angle Q and N have squares and that should mean that they are both 90 degrees. Also while vertical angels are congruent, angles Q and N are not vertical from each other, Reflexive Property is if it is a side and not an angle I think.
Answer:
<h2>x = 4</h2>
Step-by-step explanation:
ΔLMN and ΔPMQ are similar. Therefore thw sides are in proportion:
We have:
LM = 3 + 9 = 12
PM = 9
NM = x + 12
QM = 12
Substitute:
<em>cross multiply</em>
<em>divide both sides by 9</em>
<em>subtract 12 from both sides</em>
Answer:
3/10
Step-by-step explanation:
There are totally 5 disks. On the first pick, there are 3 red discs. So
P(red disc on first pick ) = 3/5
Assuming that a red disc has been picked the first time, there will be 2 red discs and 2 blue discs so
(P red disc on second pick given red disc on first pick) = 2/4
P(red disc on both picks) = 3/5 x 2/4 = 3/10
The true statements about ∠MJK and ∠MJL are
- The sum of the two angles is 180 degrees
- JK and JL are opposite rays
- JK and JL form a straight line
<h3>How to determine the true statements?</h3>
The statement is given as:
∠MJK and ∠MJL are a linear pair of angles and the angles are also supplementary
As a general rule, linear pair angles are adjacent angles that add up to 180 degrees. This means that:
- They are supplementary angles
- They have a sum of 180 degrees
- The angles may or may not be congruent
- They have opposite rays i.e. straight line
The above means that, the following options are true:
(e), (f) and (h)
Also, the converse of the statement is:
∠MJK and ∠MJL are supplementary angles and the angles are also linear pair of angles
This is false because not all supplementary angles are linear pair angles
