Answer:
AD = 6.76 inches
Step-by-step explanation:
Taking the triangle ABC:
tan 45° = AB/BC
1 = AB/BC
AB = BC = 16 in
Taking the triangle DBC:
tan 30° = DB/BC
DB = BC * tan 30°
DB = 16 * tan 30°
DB = 9.24 in
Given that AD + DB = AB, then
AD = AB - DB
AD = 16 - 9.24 = 6.76 inches
72 triangles will be displayed I believe....
All you do is multiply 2 times 36 and you get 72. Because there are 2 triangles in one square, so 2*36.
Hope this Helps!
Answer:
y = - 4x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - 4 and y- intercept = (0, 2) ⇒ c = 2
y = - 4x + 2 ← equation in slope- intercept form
Answer: No, Asher is incorrect. Instead of subtracting 4 from both sides, you should divide by 4. As a result, x should equal 16, not 60.
Divide by 4 to both sides.
Perimeter (P)
P= a+b+c
P=6.5+6.5+9
P=13+9
P=22ft
Area
A=h•b/2
A=4.7 •9/2
A=42.3/2
A=21.15 ft^2
