X=7 so that means replace all the x values with 7
7^3+5(3)= the answer solve it
7 square 3 + 5 times 3 equal
Vertex angle = x
1 base angle = 1/2x - 8
180-x = (1/2x-8)x2
180-x = x-16
196-x = x
196 = 2x
x=98
If you want explanation please ask me .
can you give more detail?
The circumference is about 3.14 (

) times bigger than twice the radius. Mathematically, this can be writted as

, where C equals the circumference and r equals the radius, or

where C equals the circumference and d equals the radius.
Answer:
8
Step-by-step explanation:
2 * 8 = 16
