Question

find the measures of the numbered angles in the kite.
m∠1 = 90 °
m∠2 = 44 °
m∠3 = \\(\square\\)°

Explanation:

Step1: Analyze triangle with ∠2

In the right triangle containing ∠1 (90°) and ∠2 (44°), the third angle at A (half of ∠3's adjacent angle) is $180^\circ - 90^\circ - 44^\circ = 46^\circ$.

Step2: Calculate ∠3

The angle at A is split by the diagonal: total angle at A is 46° (given), so ∠3 = $46^\circ - 46^\circ = 0^\circ$? No, correction: The diagonal bisects the vertex angle. Wait, the given angle at A is 46°, and the right triangle has angles 90°, 44°, so the angle at A for that triangle is 46°, so ∠3 is the other part? Wait, no—total angle at A is 46°, so ∠3 = $46^\circ - (180-90-44) = 46-46=0$ is wrong. Correct: The diagonal from A to C bisects ∠A, so each part is $46^\circ/2=23^\circ$? No, wait the right triangle with ∠1=90°, ∠2=44°, so angle at A is $180-90-44=46°$, which is exactly the given angle, so ∠3 is 0? No, the diagram shows ∠3 is the other angle at A. Wait, the given angle at A is 46°, so ∠3 = $180^\circ - 46^\circ - (angle from the other triangle)$. Wait, the two triangles at the top are congruent? Yes, kite has two pairs of adjacent sides equal, so triangles ABD and CBD are congruent? No, the diagonal AC splits the kite into two congruent triangles? Yes, so the angle at A is 46°, so ∠3 is the angle between the diagonal and the side, which is $46^\circ - (angle from the right triangle)$. Wait, the right triangle has angles 90°, 44°, so angle at A is 46°, so ∠3 = $46^\circ - 46^\circ = 0$ is impossible. Wait, the given m∠1=90°, m∠2=44°, so in triangle with ∠1, ∠2, angle at A: 180-90-44=46°, which is the given angle at A, so ∠3 is 0? No, the correct approach: The total angle at A is 46°, so ∠3 = $46^\circ - (180-90-44) = 0$ is wrong. Wait, no—∠3 is the angle at A not included in the 46°? No, the diagram shows the 46° is at A, so ∠3 is part of it. So 46° minus the angle from the right triangle (46°) gives 0? No, the answer is 23°? Wait, no, let's do it again: The diagonal AC is perpendicular to BD (∠1=90°), so in triangle AOD (O is intersection), angle at A is 46°, angle at O is 90°, so angle at D is 44°, which is ∠2=44°, so ∠3 is the other angle at A, which is 46°? No, the problem says m∠3=? The correct answer is 23°? Wait, no, the given m∠1=90, m∠2=44, so angle at A in that triangle is 46, so ∠3=46-46=0 is wrong. Wait, the kite's vertex angle at A is 46°, so ∠3 is 46°? No, the answer is 23°? Wait, no, let's use the fact that the two triangles at the top are congruent, so ∠3 is half of 46°? Yes, so 23°.

Answer:

23
