Which expression can be simplified to find the slope of the trend line in the scatterplot? PLEASE HEL AND PLEASE HURRY On a graph, a line goes through points (4, 21) and (8, 35).

A.)StartFraction 21 minus 35 Over 8 minus 4 EndFraction

B.)StartFraction 8 minus 4 Over 21 minus 35 EndFraction

C.)StartFraction 35 minus 21 Over 8 minus 4 EndFraction

D.)StartFraction 8 minus 4 Over 35 minus 21 EndFraction

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.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
