Please help me on dis question
lara [203]

Answer:

a) See below

b) \huge\boxed{\sf Area\ of\ each\ triangle = 62.4\ in.\²}

c) \huge\boxed{\sf Area\ of\ the\ table = 374.4\ in.\²}

Step-by-step explanation:

<u>Part A:</u>

We can draw 3 lines from A to D, B to E and F to C such that all of the lines pass from the center. This will form 6 equal (congruent) triangles.

\rule[225]{225}{2}

<u>Part B:</u>

Area of each triangle = 1/2 (Base)(Height)

Where Base = 12 in. and Height = 10.4 in.

Area = 1/2 (12) (10.4)

Area = 6 (10.4)

Area of each triangle = 62.4 in.²

\rule[225]{225}{2}

<u>Part C:</u>

Since the table is mage up of 6 equal triangles:

So,

Area of the table = 6 (Area of each triangle)

Area of the table = 6 (62.4)

Area of the table = 374.4 in.²

\rule[225]{225}{2}

Hope this helped!

Find the equation of the line through the point (–2, –2) that is perpendicular to the line y = 2x – 1.
Verizon [17]
For lines to be perpendicular to each other their slopes must be negative reciprocals of one another, mathematically:

m1*m2=-1  

Since y=2x-1 has a slope of 2, our perpendicular line must have a slope of:

2m=-1, m=-1/2, so our perpendicular line will be of the form:

y=-x/2+b, using the point (-2,-2) we can solve for the y-intercept, or "b".

-2=--2/2+b

-2=1+b

b=-3, then our perpendicular line is:

y=-x/2-3 or more neatly

y=-0.5x-3
