In the diagram, TRV ≅ VRW. What is the measure of SRT? mSRT = degrees
1 answer:
If this is the correct attachment of the problem, the <span>measure of SRT in degrees is 90 degrees.
Lines TW and SV are perpendicular lines that meet on point R. These lines are called perpendicular lines because they intersect at a right angle.
So, </span><span>TRV ≅ VRW means each is measured at a 90 degree angle.
TRS and SRW are also congruent and each measures 90 degrees.</span>

Answer:
A) 6.32 in.
B) 71.56°
C) 36.88°
Step-by-step explanation:
To solve each part of the problem, let's pay attention to the triangle ABC shown in the figure.
A) The slant height (l) of the cone is the hypotenuse of the right triangle ABC, then, to calculate it you can apply the Pythagorean Theorem:
B) The angle asked is the angle ∠A, then, you have:
∠°
C) The angle formed between the segments (which you can call α) that represent the slant heights is twice the angle ∠C.
By definition, the sum of the interior angles of a triangle is 180°,so you can calculate the angle ∠C as following:
∠
Then:
°
