Answer:
b = 55°
c = 35°
Step-by-step explanation:
b° = 180° - (85°+40°) = 180° - 125° = 55°
c° = 180° - (b°+90°) = 180° - (55°+90°) = 180° - 145° = 35°
Answer:
The original height of the tree is 18 m.
Step-by-step explanation:
Please see attached photo for explanation.
From the diagram, we shall determine the value of 'x'. This can be obtained by using the pythagoras theory as follow:
x² = 5² + 12²
x² = 25 + 144
x² = 169
Take the square root of both side
x = √169
x = 13 m
Finally, we shall determine the original height of the tree. This can be obtained as follow.
From the question given above, the tree was broken from a height of 5 m from the ground which form a right angle triangle with x being the Hypothenus as illustrated in the diagram.
Thus, the original height of the will be the sum of 5 and x i.e
Height = 5 + x
x = 13 m
Height = 5 + 13
Height = 18 m
Therefore, the original height of the tree is 18 m.

Answer:
432
Step-by-step explanation:
number of :cows =32
: sheep=12×32 =384
: goats = 1345+384=1728
if he seal 3/4 of his goat ........
3/4×1728= 1296
the remained goat is :
1728-1296=432
we know that property of in center we get
DW = FW = EW
compare the equations and solve for x:
DW = FW
7x - 13 = 15x - 37
15x - 7x = 37 - 13
8x = 24
x=24/8
x = 3
now
DW = 7x - 13 = 7×3 - 13 = 8 units
The measure of WE is same as DW=WE = 8 units
