Question

Вычисли ∢CBA, если ∢DBC=43° и ∢ABD=90°.. LŠt.PNG ∢CBA= °

Answer 1

СВА=DBC+ABC=43+90=133

Answer 2

Based on the given diagram, we know that:

• ∢ABD = 90° (given)
• ∢DBC = 43° (given)
• ∢ABD + ∢DBC + ∢CBA = 180° (angle sum of triangle ABC)

Substituting the given values, we get:

90° + 43° + ∢CBA = 180°

Simplifying the equation, we get:

∢CBA = 180° - 90° - 43° = 47°

Therefore, ∢CBA is 47°.
