Use the diagram shown. There are two lines which intersect each other and making angles 1 and 2. The opposite angles to 1 is 3, and 2 is 4. Which statements are true? Select all that apply. A. m∠2 + m∠3 = 180° B. m∠3 + m∠4 = 180° C. m∠2 + m∠3 = m∠3 + m∠4 D. m∠1 + m∠3 = m∠2 + m∠4

i believe that is true.

step-by-step explanation:

hope my answer has you if not i'm sorry.

ok

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
