Figure ABCD is graphed on a coordinate plane.
Phoenix [80]
1. BC is 1+3=4 (units)

2. AD is 3+5= 8 (units)

3. Draw the altitude CH from point C, as shown in the figure.

4. Then triangle CHD is a right triangle, with hypothenuse CD, and sides HD and CH.

5. CD^2=HD^2+CH^2

CD^2=2^2+4^2=4+16=20

CD= \sqrt{20}= \sqrt{4*5}= \sqrt{4} *  \sqrt{5}=2 \sqrt{5}= 4.47

6. AB=CD=4.47 because the trapezoid is isosceles.

7. P= BC+AD+AB+CD=4+8+4.47+4.47=20.9 (units)

A. Describe two ways to find product 4.2 (6+ 0.43)
weqwewe [10]

First method:

What we can do first is to distribute directly 4.2 to 6 and 0.43, that is:

4.2 (6 + 0.43)

= 4.2 * 6 + 4.2 * 0.43

= 25.2 + 1.806

= 27.006

 

Second method:

We can add the two numbers 6 and 0.43 then multiply with 4.2, that is:

4.2 (6 + 0.43)

= 4.2 (6.43)

= 27.006

 

What we see is the Distributive Property of multiplication which states that multiplying the sum of a number is similar to multiplying each number and then adding the products.

Lines are cut by transversal such that the alternate interior angles have measures of 3X +17 X +53°
Anna11 [10]
Di you leave out some parenthesis? This looks like 3x+17x+53, which is the same as 20x+53? That is not enough information to solve. however, if you meant one angle was 3x+17 and the other was x+53, just set the two equal to each other to solve for x, then plug that into one of the equations to find the measurement of the angle.
