Angle a and b are supplementary angles which means that when added they equal 180.
so we must set our equation equal to 180.
8x+74+2x+56=180
which simplifies to 10x+130=180
then subtract 130 from both sides.
10x=50
x=5
So we plug in 5 to find the measure of b.
2(5)+56=b
10+56=b
66=b
the measure of angle b is 66 degrees
Answer:
1017.4 m³
Step-by-step explanation:
Volume of cone V = (1/3)πr²h
pi = 3.14
r = 9 and r² = 81 m²
h = 12 m
V = (1/3)*3.14*81*12
V = 1017.36 rounded 1017.4 m³, which is the first answer.
9514 1404 393

640 marks
Step-by-step explanation:
80% of 800 is ...
0.80 × 800 = 640
He got 640 marks.
Animators can create mountains using fractal geometry.
They create these mountains by breaking large triangles into smaller and smaller triangles, as a result, these large triangles end up looking like mountains.
An animator became a millionaire because he discovered this. He sold his mountain animations to air travel companies who wanted to place photographs of planes behind mountains in their advertisements.
It would've been expensive to take photos of planes behind real mountains, so these air travel companies decided to buy this animator's animations of mountains in order to save money.
What happened to this animator? Well he got hired by Pixar to help create the movie Toy Story and became even wealthier.
