4(2x+5)-8 = 36
8x+20-8 = 36
8x = 24
x = 3
Curved surface area of a sphere =1256 cm

=
4×3.14
1256
⟹r

=100
∴r=10 cm
Hence, the answer is 10 cm.

Answer:
30 beads to be exact your welcome
Step-by-step explanation:
Answer:
x = 58°
z = 60°
y = 29( 58°)
Step-by-step explanation:
The arrows on the lines are trying to tell you that these lines are parallel to each other, whenever you see parallel lines think of *FUN* method
2y = 58° (alternate angles)
y = 29
x = 58° (alternate angles)
62° + 58° + z = 180° (sum of angles on a triangle)
120° + z = 180°
z = 60°
