For trapezoid JKLM, A and B are midpoints of the legs. Find AB.

romanna [79]

Answer:

Step-by-step explanation:

The length of the median of a trapezoid equals one-half the sum of the lengths of the bases.

$\begin{array}{rcl}AB & = & \frac{1}{2}(JK + LM)\\\\& = & \frac{1}{2}(19 + 39)\\\\& = & \frac{1}{2}\times 58\\\\& = & \mathbf{29}\\\end{array}$

There are federal excise taxes on the retail price when purchasing fishing equipment. the taxes are intended to help pay for par

Marizza181 [45]

Using proportions, it is found that the federal tax rate is of 10%.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The tax rate is the <u>proportion that $17.50 is of $175</u>, hence:

r = 17.50/175 = 0.1 = 10%.

The federal tax rate is of 10%.

Find the area of △ABC with side lengths b = 6 and c = 17, and included angle A = 135∘. Round your answer to the nearest tenth

Cloud [144]

Answer:

<u>Area = 36.1 sq. units</u>

Step-by-step explanation:

We will use the "included angle area" formula for a triangle to solve this problem.

The formula is:

$A=\frac{1}{2}abSinC$

Where

a and b are the two sides given

C is the angle given BETWEEN the two sides

From the problem, we can write:

the two sides are 6 & 17, so that will be "a" and "b" of the formula

the included angle is 135, so that will be "C" of the formula

Substituting, we find the answer:

$A=\frac{1}{2}abSinC\\A=\frac{1}{2}(6)(17)Sin(135)\\A=36.06$

Rounded to 1 decimal place,

<u>Area = 36.1 sq. units</u>
