Answer:
(A) 2 meter
Step-by-step explanation:
It is given that the ladder forms a 72º angle with the ground and rests against the house at a spot that is 6 meters high.
Let the measure of bottom of the ladder from the wall be x, then using the trigonometry, we have
≈
Thus, option A is correct.
The number that will be immediately filled before 32754 is 32658
Option E is correct.
We know the CE = 10x + 18 and DE = 7x - 1 and D is the midpoint of CE
⇒ CE = 2 * DE
⇒ 10x + 18 = 2 * (7x - 1)
⇒ 10x + 18 = 14x - 2
⇒ -4x = -20
⇒ x = 5
Now we also know that BC = 9x - 3 and AC = CE = 10x + 18
⇒ AB = AC - BC
⇒ AB = 10x + 18 - (9x - 3)
⇒ AB = x + 21
Substituting the value of x,
⇒ AB = 5 + 21
⇒ AB = 26
Hence, the value of AB is 26 units.
386 x 21 = 8.106
I hope you got a good grade on your assignment!!! :D
Answer:
z=-7
Step-by-step explanation:
-9+8*14z+8*2=7*17z+7*8
-9+112z+16=119z+56
112z+7=119z+56
-112z -112z
7=7z+56
-56 -56
-49=7z
:7 :7
z=-7
