can anyone give me trigonometric formula (i. e. Cot A = cosA/SinA.) pls if you understand give me all the forumulas of it. Thank you so much.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

4.

step-by-step explanation:

it have the same area.brainliest

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.

nope.   happens to me as well.
