Rectangle has diagonal of 28 and forms a60 degree angle with the bases what are the side lengths
1 answer:
Sine (28) = opposite / hypotenuse = 0.46947 = opposite / 28 opposite = 0.46947 * 28 <span><span><span>opposite side = 13.14516
</span>
</span>
</span>
cosine (28) = adjacent / hypotenuse = 0.88295 = adjacent / 28 adjacent = 28 * .88295 <span><span><span>adjacent side = 24.7226
</span>
Double Check </span>
</span>
<span>13.14516^2 + 24.7226^2 = 28^2 </span> <span>

It's 106° because those the angle given and the angle they're asking for are corresponding angles
Answer: C) ASA = ASA
Refer to the diagram below. I've used color coding to match up the given statements with the drawing. Note how the red segments are between the blue and green angles. So we use ASA to prove the triangles are congruent.

Answer:
Step-by-step explanation:
Hey there!
The range is the possible y values, so the range of this graph would be all real numbers less than or equal to -5.
