Answer:
$15
Step-by-step explanation:
Range is the difference of the highest and lowest data.
Based on the given $20 is the highest and $5 is the lowest.
$20 - $5 = $15
Answer:If the vertex angle is x, then the base angle is 2x. Since the base angles of an isosceles triangle are equal, the other base angle is 2x.
The sum of the angles of a triangle are 180 so: x + 2x + 2x = 180 and x = 36 and 2x = 72.
Thus, the vertex angle is 36 degrees and the two base angles are 72 degrees each.

Answer:
Step-by-step explanation:
8r + 9 + 7r + 6 = 90
15r + 15 = 90
15r = 75
r = 5
8(5) + 9 = 40 + 9 = 49
7(5) + 6 = 35 + 6 = 41

Answer: 19.1</h3>
====================================================
Work Shown:
tan(angle) = opposite/adjacent
tan(C) = AB/BC
tan(theta) = x/BC
tan(23) = (8.1)/BC
BC*tan(23) = 8.1
BC = (8.1)/tan(23)
BC = 19.0824041631723
BC = 19.1
In this case, rounding to 3 sig figs means we round to the nearest tenth.
Make sure your calculator is in degree mode.
