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:
Answer: -6b + 5 here you go have a great day:)
Answer:
B
Step-by-step explanation:
I just had the same paper last night
~Hello There!~
Find the total number of marbles first
2 + 3 = 5
Keep this number in mind as it will be your denominator for your result
There are 2 blue marbles, therefore, the final answer will be:
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^

Answer:
Step-by-step explanation:
Acute triangle : 0<x<90 degrees
right triangle : x=90 degrees
obtuse triangle :triangles that angles are bigger than 90 but smaller than 180 degrees
reflex angle:bigger than 180 but smaller than 360 degrees
