Angle sum of a triangle = 180°

Type of Triangle: Isosceles.
Therefore, 2 of the angles are equivalent.

2x = 50
2 ( 25 ) = 50
50 = 50

Meaning that the sum of the 2 angles is 100°.

( 5y + 10 ) + 2x + 50 = 180
5y = 180 - 100 - 10
5y = 70
y = 70 / 5
y = 14°

ANSWER:
y = 14°

AnnyKZ [126]

Answer:

40cm

Step-by-step explanation:

The formula to find the circumference is :

Here,

d ⇒ diameter

Given that,

Circumference = 125.6cm

<u><em>Now let us find the diameter of the circle.</em></u>

C = π × d

125.6 = 3.14 d

Divide both sides by 3.14.

<u>40 cm </u>= diameter
