Answer: y = 5
Step-by-step explanation:
This triangle is isosceles.
So, ∠ABC = ∠ACB = 75°
Now,
sum of interior angles of a triangle = 180°
∠ABC + ∠ACB + ∠BAC = 180°
75° + 75° + (4y + 10)° = 180°
160° + 4y° = 180°
4y° = 20°
y = 5

Answer:
D) 50/3
Step-by-step explanation:
6/10 = 10/(6+x-6)

x = 100/6
x = 50/3
Answer:
2 (B)
Step-by-step explanation:
Area of circle formula= pi r^2
Radius of circle= diameter / 2
radius= 6
3.14x6^2 = about 113.04
Volume= base x height
So, height = volume/base
226/113.04 = 2
Answer= B. 2
