The answer is 7
Step-by-step explanation:
We know than Tan45=1
Tanx=opp/adj
tan45=y/(7
)/2
Thus y=7/2
We know by pythagoras theorem that hyp^2=side^2+side^2
=(
+
=(49(2)/4)+(49(2)/4)
=(49/2)+(49/2)
=(98/2)
=49
x=7

<h2>X=-6</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>let's solve:</h3>
- add 12 to both sides:-5x-12+12=18+12=>-5x=30
- divide both sides by-5:-5x/-5=30/-5
- therefore x=-6
23 is a prime number because it is only divisible by (has factors of) 1 and itself (23).
27 is NOT a prime number because it is divisible by more than 1 and itself (also 3 and 9).
29 is a prime number because it is only divisible by 1 and 29.
