They are both right triangles so we can use the Pythagorean

theorem to solve.

Answer:

6) b = 12mm

7) b = 24cm

Step-by-step explanation:

6) To find b, you will subtract the square root of the square of 9mm from the square of 15mm

i.e. b = \sqrt{(15mm)^{2} - (9mm)^{2}  }

b = \sqrt{225mm^{2} - 81mm^{2}  }

b = \sqrt{144mm^{2} }

b = 12mm

7) To find b, you subtract the square root of the square of 10cm from the square of 26cm

i.e. b = \sqrt{(26cm)^{2} - (10cm)^{2} }

b = \sqrt{676cm^{2} - 100cm^{2}  }

b = \sqrt{576cm^{2} }

b = 24cm
