Answer:

z = 92

x = 11

Step-by-step explanation:

From the figure,

13x - 55 = 88 (Opposite angles made by two straight lines are equal)

13x = 88 + 55

13x = 143

x = 143/13

x = 11

Again,

88 + z = 180 (Sum of angles of a straight line)

z = 180 - 88

z = 92

VladimirAG [237]

Answer:

J and K are supplementary

Step-by-step explanation:

Given

The attached image

Required

The true statement

From the attached image, it is hard to determine the values of angles I and L as there are no enough information to determine their values.

However, J and K can be worked easily.

From the image

J = 65^o --- vertically opposite angles

And:

K + 65^o = 180^o ---- angle on a straight line

Substitute: J = 65^o

K + J = 180^o

When two angles add up to 180, the angles are supplementary.

<em>Hence, (c) is correct</em>
