Answer:
B. 84.46°
Step-by-step explanation:
Since the vectors are at right angles to one another, even a crude diagram will quickly show you that the direction of the sum is ...
30° + arctan(7/5) ≈ 84.4623° ≈ 84.46°
Answer:
10
Step-by-step explanation:
You can do 5+5=10 or you can do 5x2=10. You can also do it this way but it is the longer way 1+1+1+1+1+1+1+1+1+1.
Answer:
no solution
Step-by-step explanation:
when you substitute for the equation is false
how I solved this:
1. substitute for
2. distribute the 3
3. combine like terms
this is incorrect because 12 does not equal -12, so there is no solution
Answer:
if 5=70
2=?
cross multiply=28
add 70+28=98
Step-by-step explanation:
Answer:
It is quite simple.
Step-by-step explanation:
Here it given PR = RQ
Also ang P=ang Q
RS is the median. That is the hard part for u, I know.
A median of a triangle divides it into 2 parts of equal area. So here it divides PQ into 2 equal parts as RS is the median.
So PS=QS
Ang P=Ang Q
PR=RQ
From all this we can say that Triangle PRS congruent Triangle QRS.
