Question

g the tiles to the boxes to form correct pairs. not all tiles will be used.
with reference to the figure, match the angles and arcs to their measures.
124° 122° 114° ∠oca ∠cob 58° ∠eob
∠dfa 𝑪𝑬̂

Explanation:

Step1: Find $\angle COB$

$\angle COB = 180^\circ - 114^\circ = 114^\circ$

Step2: Find $\angle EOB$

$\angle EOB = 180^\circ - 124^\circ = 124^\circ$

Step3: Find $\overset{\frown}{CE}$

$\overset{\frown}{CE} = 360^\circ - 114^\circ - 124^\circ = 122^\circ$

Step4: Find $\angle DFA$

$\angle DFA = \frac{1}{2}(114^\circ + 124^\circ - 122^\circ) = 58^\circ$

Answer:

1. $\angle COB \longleftrightarrow 114^\circ$
2. $\angle EOB \longleftrightarrow 124^\circ$
3. $\overset{\frown}{CE} \longleftrightarrow 122^\circ$
4. $\angle DFA \longleftrightarrow 58^\circ$
