Question

Find the missing length of the triangles.

Answer 1

They are both right triangles so we can use the Pythagorean

theorem to solve.

6. B = sqrt(15^2-9^2)

B = 12 mm

7. B = sqrt(26^2-10^2)

B = 24 Cm

Answer 2

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
