Question

A parallelogram has one angle that measures 170. What are the measures of the other three angles in the parallegram

Answer 1

let

a= 170°

therefore c = 170° (opposite angles)

now a+b = 180° (co- int angle)

b= 10°

d=10° (opposite angle)

Answer 2

The four angles of parallelogram are 170, 10, 170 and 10 degrees.

Step-by-step explanation:

We are given the following in the question:

A parallelogram has one angle that measures 170.

Properties of a parallelogram:

• Opposite angles of a parallelogram are equal.
• Adjacent angles of a parallelogram are supplementary.

Let the adjacent angle be x, then

$x + 170 = 180\\x =10$

Thus, the four angles of parallelogram are 170, 10, 170 and 10 degrees.
