Answer:
DB = CA (Proved)
Step-by-step explanation:
Statement 1.
∠D = ∠C, M is the midpoint of DC and ∠1 = ∠2
Reason 1.
Given
Statement 2.
Between Δ DBM and Δ CAM,
(i) DM = CM,
(ii) ∠D = ∠C and
(iii) ∠DMB = ∠CMA
Reason 2.
(i) given
(ii) given and
(iii) ∠ DMB = ∠1 + ∠AMB and ∠CMA = ∠2 + ∠AMB
Since ∠1 = ∠2, so, ∠DMB = ∠CMA.
Statement 3.
Δ DBM ≅ Δ CAM
Reason 3.
By angle-side-angle rule.
Statement 4.
DB = CA
Reason 4.
Corresponding sides of two congruent triangles. (Answer)
Answer:
729 in ^3
Step-by-step explanation:
Answer:
1. I don't know how to solve that sorry :(
2. B. It is a diameter
3. 30° = q
4. I don't know sorry :(
Step-by-step explanation:
1. I don't know how to solve that sorry :(
-----------------------------------------------------------
2. B. It is a diameter
------------------------------------
3. All triangles = 180°
180° = 60° + 90° + q
180° = 150° + q
180° - 150° = 150° - 150° + q
30° = q
180° = 60° + 90° + 30°
180° = 150° + 30°
180° = 180°
------------------------------------------
4. I don't know sorry :(
