kiruha [24]

Answer:

JK≅MN, KL≅NO and ∠K≅∠N

Step-by-step explanation:

we know that

A Reflection is a transformation that doesn't change the size or shape of the figure

Triangle JKL and triangle MNO are congruent

The corresponding sides and the corresponding angles are congruent

therefore

JK≅MN, KL≅NO,JL≅MO

and

∠J≅∠M, ∠K≅∠N,∠L≅∠O

In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angl

Dmitry_Shevchenko [17]

Answer:

The value of x is 50°.

Step-by-step explanation:

We know that:

x = y
2(70 + 60) + x + y = 360

Work:

2(130) + x + x = 360
=> 260 + 2x = 360
=> 2x = 360 - 260
=> 2x = 100
=> x = 50

Hence, the value of x is 50°.

Hoped this helped.

an ice fisherman wishes to cut a hole in the ice which has a diameter of 30 cm. How far around must he cut to create this hole?

olga55 [171]

Given:

Diameter of the hole = 30 cm

To find:

The area of the hole.

Solution:

The radius of a circle is always half of the diameter. It is given that the diameter of the hole is 30 cm. So, the radius of the hole is:

$r=\dfrac{30}{2}$

$r=15$

Area of a circle is:

$A=\pi r^2$

Putting $\pi = 3.14$ and $r=15$ in the above formula, we get

$A=(3.14)(15)^2$

$A=(3.14)(225)$

$A=706.5$

Therefore, the area of the hold is 706.5 square cm.
