Answer:
1) 36 + 50 = 86 : Addition property of equality
2) m<D = m<ADB : If two angles have the same measure, then they are equal.
3) <D congruent to <ADB : if two angle are equal, then they are congruent.
4) <D, <ADB are alternate interior angles: assumed from diagram
5) <u>CD // AB</u> : if alternate interior angles are congruent, then the 2 lines cut by a transversal are //.
6) 130 + 50 = 180 : addition property of equality
7) m<E, m<BAE are supplements : if the sum of two angles equal to 180, then they are supplements.
8) <E, <BAE are same-side interior angles : assumed from diagram
9) <u>EF // AB</u> : if same-side interior angles are supplements, then the 2 lines cut by a transversal are //.
10) <u>CD // EF </u>: if two lines are // to the same line, then they are //.
im pretty sure this is the proof
I can and will help if you give me something to help with.
Answer:
60
Step-by-step explanation:
you multiply 150*4 then divide that by 10 and that's your answer
The area of a sector of a circles is calculated by the equation A = πr^2 (theta/360). From the data of the sector, we determine the radius of the circle. THen, we can calculate for the area of the circle.
16.4π = πr^2 (72/360)
r = 9.06
Area of circle = πr^2
Area of circle = π(9.06)^2
Area of circle = 82π
