- sin∅ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define variables</u>
∅ = 39°
opposite leg = 9
hypotenuse = x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: sin39° = 9/x
- Multiply <em>x</em> on both sides: xsin39° = 9
- Isolate <em>x</em>: x = 9/sin39°
- Evaluate: x = 14.3011
- Round: x ≈ 14.30
Answer:
R=9
Step-by-step explanation:
Change the sign of -2 to 2
Add 2 to 7
131.3312, and if rounded 131
They are congruent. I believe it is ASA because both triangles have two angles identical to the other triangle with shows it had equal angles so using process of elimination I’m assuming it’s ASA because it includes two angles lol
