20 tens ? Because 10x2 tens
So for 12.5 meters...the little guy walks 5 meters per minute....
<span><span><span>12.5meters</span><span>5<span><span>meters</span><span>minute</span></span></span></span>=2.5minutes</span>
we can check it by saying...okay...if his speed was 5 meters per minute....and he walked for 2.5 minutes...does he walk 12.5 meters?
<span>5×2.5=12.5</span><span>
so yes it checks out :)</span>
Corresponding altitudes are corresponding parts. They are congruent because ... Corresponding parts of congruent triangles are congruent. (CPCTC)
Answer:
The measures of ∠BOC is 25.4° and that of ∠AOB is 15.8°.
Step-by-step explanation:
Given that,
∠AOC = 31°
∠BOC = 2x+10
∠AOB = 4x-15
As we can seen from the figure that,
∠AOC = ∠AOB + ∠BOC
Put all the values,
31 = 4x-15+2x+10
31 = 6x-15
31+15 = 6x
46 = 6x
x = 7.7
∠BOC = 2(7.7)+10 = 25.4°
∠AOB = 4(7.7)-15 = 15.8°
So, the measures of ∠BOC is 25.4° and that of ∠AOB is 15.8°.
