Firstly, we need to find m<BCA
<BCA+<BCD=180°
m<BCD=111°
<BCA+111°=180°
m<BCA=69°
Secondly, we need to find y
The sum of all angles of triangle is equal to 180°, so
Now we can find m<B
m<B=(3y+6)°
y=15
m<B=3×15+6=51°
Answer: m<B=51°
Answer:
92/85
Step-by-step explanation:
Height of Dougal = 1.84 meters
Height of Seb = 1.7 meters
Height of Dougal as a fraction of height of Sab =
= [Simplify the fraction]
=
=
Therefore, fraction of heights will be = 92/85
Answer:
The specific latent heat.
Answer:
Step-by-step explanation:
<u>Minimum number of regions</u>
You may have 100 parallel lines. This will give us 101 regions
<u>Use following formula to find the maximum possible number of regions:</u>
- R(n) = 1 + n(n + 1)/2, where n is the number of lines
- R(100) = 1 + 100*101/2 = 5051
