2 separate 7 ft boards = (2 * 7) = 14 feet
1 ft = 12 inches....so 14 feet = (14 * 12) = 168 inches
168/11 = 15.27 <== she has 15 eleven inch boards.
Answer:
Step-by-step explanation:
with a 45-45-90 triangle the hypotenuse is equal to the length of one of the legs times the square root of 2.
if one of the legs is 1.2 than the hypotenuse of this triangle should be
1.2* sqrt(2) = about 1.7
Answer
=12/13
Step-by-step explanation:
I have done it before:)
∠1 and ∠3 complementary,
∠1 = ∠2,
so
∠1 and ∠2 complementary.
Answer : C.
Answer:
8 cm
Step-by-step explanation:
the 3 cm line from the chord to the center of a circle is a leg of a right triangle which perpendicularly bisects the chord into two equal halves
draw the hypotenuse of the right triangle from the center of the circle to the endpoint of the chord. This is a radius measuring 5 cm.
find the missing leg of the right triangle
a^2= c^2- b^2
a^2= 25-9
a^2=16
a=4
this is only the measurement of half the chord. To find the full length of the chord multiply by two
4*2=8 cm
