A. The angles at the intersection of the two lines can be proven to be congruent and complementary . so they meet at a right angle and the lines are perpendicular.

Step-by-step explanation:

In above question, In order to find whether AB ⊥ CD, Using compass construction & rounder , keep the tip at A and cut arcs at line CD . Follow the same process again with tip at B and cut arcs at line CD . Do this both sides of Line CD i.e. on left side of AB & on right side of AB. Now, join the intersection points of both side arcs which are intersecting each other. Now, to prove both are right angle to each other i.e. AB ⊥ CD , can be done by proving congruent and complementary , so they meet at a right angle and Hence , the lines are perpendicular i.e. AB is inclined to CD at angle of 90°.

5/4=y−1/4 y=_____ What is the answer?

Nat2105 [25]

In this equation, you are solving for y. Simply isolate the variable by adding 1/4 to each side. The -1/4 and 1/4 will cancel out on the right side of the equation, leaving only y:

5/4 = y - 1/4

5/4 + 1/4 = y - 1/4 + 1/4

6/4 = y

y = 6/4

Don't forget to simplify y:

y = 3/2

Tom and Lana were comparing their Halloween candy. Tom received 4 times as much candy as Lana received. Tom then split his candy

seropon [69]

Given that Lana received 18 ounces of candy and Tom received 4 times as much candy as Lana received, then the number of candy Tom received is given by 4(18) = 72.

Now, given that Tom divided his candy evenly into 9 piles. Then the number of ounces of candy in each of Tom's piles is given by:

72/9 = 8 ounces.

That's an easy parallelogram, parallel to the x axis. Let's label the points

A(-4,-1),B(-2,4),C(4,4),D(2,-1)

AD and BC are the sides parallel to the x axis. We'll call those the base, it has length 4 - -2 = 6.

The height is the change in y between the bases, so 4 - -1 = 5.

The area is base times height, 6 × 5 = 30

Answer: 30

The shoelace formula gives us the area of a polygon from 2D coordinates without worrying about the shape:

(-4,-1),(-2,4),(4,4),(2,-1)

(-2,4),(4,4),(2,-1),(-4,-1)

$A = \frac 1 2 | -4(4) - (-1)(-2) + (-2)(4) - 4(4) + 4(-1) - 4(2) + 2(-1) - (-1)(-4) |$

$A = \frac 1 2 |-60| = 30 \quad \checkmark$
