Remember: Standard formula
a x 10^b
Answer:
B
Step-by-step explanation:
a²+b²=c²
3²+b²=5²
b²=5²-3²
b²=25-9=16 answer is 16
Using the law of sins:
side a / sin (angle A) = side b / sin(Angle B)
Side a is opposite angle A, so from the picture we know side a = 50, angle A is 58 degrees and angle B is 48 degrees.
replace those values in the formula we get:
50 / sin(58) = b/ sin(48)
so now we can cross multiply the 2 fractions to get:
50 * sin(48) = b*sin(58)
to get b by itself, divide both sides by sin(58) to get:
b = (50*sin(48)) / sin(58)
b = 43.82
You may need to round the answer as needed.
The side |rs| is congruent to side |ac| which is 14 ft.
<h3>What are congruent triangles?</h3>
Congruent triangles are two similar triangles that have corresponding sides and angles and they are of equal measure.
The figures from the textbook illustrate that following rotation, the two triangles are congruent.
This signifies that the angles and sides of the first triangle are equal to the angles and sides of the other triangle.
Therefore:
- ab = tr = 10 ft
- ac = rs = 14 ft
- bd = ts = 20 ft
