Question

# Compare β π
ππ and β πππ

## The correct answer is: 10 digres

- Step by step explanation:Β
- Step 1:
- Find β ROQ:

- Align the protractor with the ray OR on 90
^{o} as shown above.Β
- Start reading the outer scale from the 90Β°.
- Step 2:
- From the figure we can see that ray OR is aligned on mark 90
^{o}. And ray OQ is aligned on mark 130^{o}.

Hence, the measure of β ROQ = (130^{o} - 90^{o}).

Β β ROQ = 40^{o}.

- Step 3:
- Find β POQ:
- Align the protractor with the ray OP on 0
^{o} as shown above.Β
- Start reading the inner scale from the 0Β°.
- Step 4:
- From the figure we can see that ray OP is aligned on mark 0
^{o}. And ray OQ is aligned on mark 50^{o}.

Hence, the measure of β POQ = 50^{o}.

β POQ = 50^{o}.

- Step 5:
- Compare β POQ andΒ β ROQ

Hence, β POQ is greater thanΒ β ROQ by 10^{o}.

- Final Answer:

Hence, β POQ is greater than β ROQ by 10^{o}.

- Step 1:
- Find β ROQ:

^{o}as shown above.Β^{o}. And ray OQ is aligned on mark 130^{o}.^{o}.

- Align the protractor with the ray OP on 0
^{o}as shown above.Β - Start reading the inner scale from the 0Β°.
- Step 4:
- From the figure we can see that ray OP is aligned on mark 0
^{o}. And ray OQ is aligned on mark 50^{o}.

^{o}.
