A formula for arc length, s, given the radius, r and central angle, Ф (in radians) is s = r × Ф.
s = 8 × 3 = 24 inches
Angle A = 130° and Angle B = 110°
Solution:
Given ABCD is a trapezoid with ∠C = 70° and ∠D = 50°
If ABCD is a trapezoid, then AB is parallel to CD.
AD is a transversal to AB and CD and
BC is a tranversal to AB ad CD.
Sum of the interior angles on the same side are supplementary.
∠A + ∠D = 180°
⇒ ∠A + 50° = 180°
Subtract 50° on both sides to equal the expression.
⇒ ∠A = 180° – 50°
⇒ ∠A = 130°
Similary, ∠B + ∠C = 180°
⇒ ∠B + 70° = 180°
Subtract 50° on both sides to equal the expression.
⇒ ∠B = 180° – 70°
⇒ ∠B = 110°
Hence, angle A = 130° and angle B = 110°.
That would just mean you have to divide 15 and 7
answer:2.1 or 2pounds
Answer:
five thirteen thousandths
Step-by-step explanation:
It is decimals so it ends in ths and it has 3 places so it ends in thousandth. it is five hundred 13 so it is five thirteen thousandths
