Step-by-step explanation:
this creates a right-angled triangle.
the right angle (90°) being the angle between flag pole and ground.
the angle ground-wire is 50°.
because we know that the sum of all angles in a triangle is always 180°, we know then that the angle flagpole-wire is
180 - 90 - 50 = 40°
so, we have the situation to know 1 side and all angles.
to get the other sides we use best the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and related angles are always opposite of each other.
in our case now we have
24/sin(50) = wire/sin(90) = wire/1 = wire = 31.32977494... ft
so, the rounded answer is that the wire must be
31.3 ft long
Answer:
.79 mm^2
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 (1) ^2
A = 3.14
Now we have 1/4 of the circle
The area is 1/4 of the full area
1/4 *3.14
.785
Rounding to the nearest hundredth
.79 mm^2
2-5 inches =125miles
4-75inches=237.50 miles.
7.6=380miles
Answer:
Step-by-step explanation:
f(4) = 4-7 = -3
g(-3) = (-3)^2 = 9
Yes he is right because if u have
-6 -(-4) u would multiply the 2 signs the - and the -4 and u would get +4
then ur equation becomes -6+4 = -2
