100 meters. In a 45 45 90 triangle, both the sides are equal
value is
. Correct option is D)
.
<u>Step-by-step explanation:</u>
Here we have , expression to evaluate:

⇒ 
⇒ 
We know that ,
, putting value in equation
⇒ 
⇒ 
⇒ 
⇒ 
Therefore ,
value is
. Correct option is D)
-7y > 161......here, u would divide both sides by -7...keep in mind, when dividing/multiplying by a negative number, the inequality sign changes.
y < 161/-7
y < -23
7y > -161...here u divide by 7
y > -161/7
y > -23
