Circumference equals 9 and arc length is 1 what is the central angle?
arc length/circumference=central angle/360 1/9=central angle/360 central angle=40
Perimeter of a rectangle is 40 ft The width is 8 feet less find the length?
Perimeter = 2*(Width + Length) So 40 = 2*(8 + Length) 20 = 8 + Length Length = 12.
The measures 0f two angles of a triangle are 40 and 100 find the measure of the third angle?
The answer would actually be 40 because180-140=40.
How do you find the length of a rectangle if the perimeter is 40 and the width is 2inches?
perimeter = 2 x (length + width) ⇒ length + width = perimeter ÷ 2 ⇒ length = (perimeter ÷ 2) - width So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it. IF you meant "What is the length..." then: length = perimeter ÷ 2 - width = 40 ÷ 2 - 2 in = 20 - 2 in = 18 in
What is the complementary angle of a 50 angle?
40
What is the length of BC in this triangle angle BAC equals 40 degrees and angle ABC equals 50 degrees and angle BCA equals 90 degrees .?
In order to find length BC the length of AC or length of the hypotenuse must be given
Circumference equals 9 and arc length is 1 what is the central angle?
arc length/circumference=central angle/360 1/9=central angle/360 central angle=40
What is the measure of a central angle with a circumference of 9 and an arc length of 1?
40 degrees
Find the degree measure of angle hrp?
40
From the top of a lookout tower, a ranger spots a forest fire at a 30° angle of depression and the near end of the fire at a 40° angle of depression. The tower is 105 feet tall.Do you have enough information to find the length of the forest fire?
yes
An exterior angle at the base of an isosceles triangle measures 110 find the measure of the vertex angle?
40
Half the supplement of an angle is 12 degreees less than twice the complement of the angle Find the measure of the angle?
40 degres
What is the central angle of a circle with a circumference of 9 and arc length of 1?
2pi/9 radians or 40 degrees
A 40 degree angle is the of a 50 degree angle?
A 40 degree angle is the COMPLEMENT of a 50 degree angle.
Perimeter of a rectangle is 40 ft The width is 8 feet less find the length?
Perimeter = 2*(Width + Length) So 40 = 2*(8 + Length) 20 = 8 + Length Length = 12.
What is the measure of each base angle of an isosceles triangle if its vertex angle measures 40 degrees and its 2 congruent sides measure 25 units?
Length of sides is irrelevant. Angles are ((180 - 40)/2) ie 70o
Find the measures of an interior angle and an exterior angle of a regular polygon with 9 sides?
Each interior angle: 140 degrees Each exterior angle: 40 degrees
