Calculate .
\( ∢B \) is 2 times bigger than \( ∢A \) and\( ∢C \) is 3 times bigger than \( ∢B \).
Calculate \( ∢A \).
The triangle ABC is shown below.
angle \( ∢A=70° \).
\( \frac{∢B}{∢C}=\frac{1}{3} \)
Calculate angle \( ∢C \).
Look at triangle ABC below.
\( ∢A+∢B=2∢C \)
\( ∢B=3∢A \)
Calculate the size of angle \( \sphericalangle C\text{.} \)
The triangle ABC is shown below.
\( ∢C=2∢B \)
\( ∢B=5∢A \)
Calculate \( ∢C \)\( \).
ABC is an isosceles triangle.
DE is parallel to BC.
Angle A is equal to 3X plus 22.
Express the size of angle DEC.
