Two triangles, RPQ and NQP are placed together to create a parallelogram as shown below.

Triangles R P Q and N Q P are connected at side P Q. Angle R is 60 degrees, angle R P Q is 80 degrees, angle N Q P is 80 degrees, and angle Q P N is 40 degrees.

What is the measure of angle PQR?

m∠PQR = °

What is the measure of angle QNP?

m∠QNP = °

What is the measure of angle PQR?

m∠PQR = 40

What is the measure of angle QNP?

m∠QNP = 60

Step-by-step explanation:

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
