Answer:
2) -5/7
Step-by-step explanation:
= 
cross-multiply to get:
10 = -14n
-10/14 = n
n = -5/7 (simplified)
8 and 15 are the lengths of the legs.
The tangent is the ratio of the lengths of legs.
In general, tan x = opp/adj
You have 8/15, so here 8 is the opposite leg and 15 is the adjacent leg.
Angle A is the right angle, so that is not it.
For which acute angle, B or C, is 8 opposite and 15 adjacent?
Answer: for angle B.
Therefore, 8/15 must be tan B.
Answer:
C
Step-by-step explanation:
there is the ground line of about -5.5 to +5.5 = 11 ft.
then the 2 walls of 7 ft height = 14 ft.
that is already 25 ft.
the 2 roof sides are both a little bit longer than the corresponding ground line of 5.5ft.
so, estimated about 6ft per roof side. that adds 12 ft.
so, we are at about 37 ft.
and the closest answer is C. 36 ft.
in actual numbers a roof side is (using Pythagoras) :
roof side² = 2.5² + 5.5² = 6.25 + 30.25 = 36.5
roof side = 6.041522987... ft
so, the actual perimeter is
25 + 2×6.041522987... = 37.08304597... ft
675840 feet to go to 128 mile
I would say all of them except for the equal sign
