What is the value of d? Round your answer to the nearest tenth.

Sergeeva-Olga [200]

Answer:

11.9 mm

Step-by-step explanation:

We can find d by applying the cosine rules.

d² = 21² + 27² - 2(21)(27) cos (25)

d² = 441 + 729 - 1027.75

d² = 142.25

d = √142.25

d = 11.9 mm (nearest tenth)

Question (in need of help)

mr Goodwill [35]

<h3>Required Answer:-</h3>

This is an right angle ∆ and the side lengths containing a right angle are 9 and 11.

By Pythagoras theoram,

${p}^{2} + {b}^{2} = {h}^{2}$

where p is the perpendicular, b is the base and h is the hypotenuse.

Plugging the values,

${9}^{2} + {11}^{2} = {h}^{2}$

Then,

$h = \sqrt{ {9}^{2} + {11}^{2} }$

$h = 14.12(approx.)$

<h3>Hence:-</h3>

The x of the right angled ∆ = 14.12
