Answer:
10 units
Step-by-step explanation:
We are given that
BD=x+29
AD=x+39
AC=20
BC=x+19
AC=AB+BC
20=AB+x+19
AB=20-x-19=1-x
AD=AB+BD


Substitute the value of x=-9
Then , we get BC=
units
Answer: BC=10 units
Answer:
Option B is correct.
Step-by-step explanation:
We need to find the height of triangle.
The triangle is right angled triangle
We are given Hypotenuse = 25
Perpendicular = h
and angle Ф = 34°
We know that sinФ = Perpendicular / Hypotenuse
sin 34° = h / 25
0.56 = h/25
=> h = 0.56 * 25
=> h = 14 ft
So, the height of triangle is h= 14 ft
So, Option B is correct.
I think it’s D the answer is
Answer:
x= -6
Step-by-step explanation:
3(x+5)÷(-3)= 3÷(-3)
x+5= -1
x= -1-5= -6
x= -6
