Please answer, the question is in the photo ^^

Pr= square root of rq square + pq square

=441+784

square root of 1225

= 35 cm

35

Step-by-step explanation:

this is a right triangle and we are being asked to solve for the hypotenuse aka the diagonal or PR.

use the pythagorean theorem :

a^2 + b^2  = c^2

substitute your numbers:

28^2 + 21^2 = c^2

1225 = c^2

c = 35

*im a little confused on how PQ is longer but has a shorter length than RQ

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse

so 156= c
