SAS I think?
AB and BC are congruent
BD and BD share to same line so they are the same
Angle B is cut in half thus for they both equal so I think this is proven by SAS but I might be wrong.

Find the height of an equilateral triangle with side length 8.
Answer:
U need to just do
[tex] \sqrt{3 \div 4} a {}^{2} [/tex]
Answer:
4[tex]\sqrt{5}[/tex]
Step-by-step explanation:
The segment from a vertex to the side opposite is a perpendicular bisector.
The equilateral Δ is divided into 2 right triangles with legs 8 and 4
let height be h, then using Pythagoras' identity
h² = 4² + 8² = 16 + 64 = 80 ( take the square root of both sides )
h = [tex]\sqrt{80}[/tex] = 4[tex]\sqrt{5}[/tex] ← exact value

Which of the following graphs represents the solution set for y< -2x – 4?
Given:
The inequality is [tex]y<-2x-4[/tex].
To find:
The graph of the given inequality.
Solution:
The inequality is
[tex]y<-2x-4[/tex]
The related equation is
[tex]y=-2x-4[/tex]
For x=0,
[tex]y=-2(0)-4[/tex]
[tex]y=0-4[/tex]
[tex]y=-4[/tex]
For y=0,
[tex]0=-2x-4[/tex]
[tex]4=-2x[/tex]
[tex]\dfrac{4}{-2}=x[/tex]
[tex]-2=x[/tex]
So, the related line passes through two points (0,-4) and (-2,0).
Sign of inequality is <, so the related line is a dotted line and shaded region is below the related line.
Therefore, the correct option is B.

Answer:
83 in.^2
Step-by-step explanation:
The entire polygon consists of a rectangle with length 8 in. and width 5 in., a triangle with base 8 in. and height 7 in., and another triangle with base 5 in. and height 6 in.
The total are is the sum of the area of the rectangle and the two triangles.
area = area of rectangle + area of first triangle + area of second triangle
area = LW + bh/2 (for the first triangle) + bh/2 (for the second triangle)
area = 8 in. * 5 in. + 8 in. * 7 in. / 2 + 5 in. * 6 in. / 2
area = 40 in.^2 + 28 in.^2 + 15 in.^2
area = 83 in.^2

Step-by-step explanation:
Write 3/5 as a division
Answer:
3/5 as a division is 0.6
Step-by-step explanation:
To write a fraction as a division, we basically divide the values, since the fraction represents a division.
In this question:
We want 3 divided by 5.
3 is less than 5, so we can multiply 3 by 10(getting 30), and adding a 0 to the quotient.
So now 0.(30/5) = 0.6, which means that 3/5 as a division is 0.6.

What is the sum (2/5x + 5/8) + (1/5x - 1/4)? a. 3/5 x + 1/8 b. 3/5 x + 3/8 c. 3/5x + 5/8 d. 3/5x + 7/8
Answer:
3/5x + 3/8
Step-by-step explanation:
2/5x + 5/8 + 1/5x - 1/4
1. Combine like terms so now u have
3/5x + 3/8
In case you want to know how I got 3/8
You want a common denominator so
from 5/8 + 1/4, make both denominator 8
so 1 *2/ 4* 2
so now you converted the 1/4 to 2/8
So then 5/8 - 2/8 gives u 3/8 and that's how i got 3/8
Hope this helped!

10. One number is twenty more than eight times another number. The sum of the
numbers is eleven. Find the two numbers.
Answer:
the two numbers are 12 and -1.
Step-by-step explanation:
Let the large number be represented by x and the smaller number by y.
So that;
x = 8y + 20 .................. 1
x + y = 11 ................... 2
From equation 2,
x = 11 - y .......... 3
Substitute equation 3 into equation 1 to have,
11 - y = 8y + 20
11 - 20 = 8y + y
-9 = 9y
divide through by 9 to have,
y = -1
Substitute the value of y in equation 3,
x = 11 - (-1)
= 11 + 1
= 12
x = 12
x = 12, y = -1
The two numbers are 12 and -1.

find (4.54×10^8)-(3.98×10^8)
Answer:
[tex]5.6 *10^7[/tex]
Step-by-step explanation:
Given
[tex](4.54*10^8)-(3.98*10^8)[/tex]
Required
Solve
[tex](4.54*10^8)-(3.98*10^8)[/tex]
Apply distributive law of algebra
[tex](4.54 - 3.98) *10^8[/tex]
Evaluate the expression in bracket
[tex](0.56) *10^8[/tex]
Remove bracket
[tex]0.56 *10^8[/tex]
When a number is in standard form: [tex]a * 10^n[/tex]
The value of a must be: [tex]1 \le a \le 10[/tex]
So, the expression becomes:
[tex]5.6 *10^{-1}*10^8[/tex]
Apply law of indices
[tex]5.6 *10^{-1+8}[/tex]
[tex]5.6 *10^7[/tex]
