Dean made a triangular wall shelf.
zhannawk [14.2K]

Answer:

The shelf is not a right triangle

Step-by-step explanation:

Given

Sides = 14, 8, 8

Required

Determine if it is a right triangle

To do this, we make use of Pythagoras theorem which implies that; the square of the longest side = the sum of the square of the two other sides.

So, we have:

14^2 = 8^2 + 8^2

Evaluate all squares

196 = 64 + 64

196 = 128

The above is not true because:

196 \ne 128

<em>Hence, the shelf is not a right triangle</em>

Can someone explain how to do this? thank you!
Alisiya [41]
The answer will be <span>Negative

Write sin(</span>\frac{5 \pi }{4}) as sin(\pi+\frac{ \pi } {4}<span>)

Using the summation identity will be:
</span>=sin(\pi)+cos(\pi)sin(\frac{ \pi }{4}<span>)
</span><span>
By following the trivial identity, you should get:
=</span>0*\frac{ \sqrt{2}}{2}+(-1) \frac{\sqrt 2} {2}

<span>Remove the parentheses on -1, then multiply</span>
=0*\frac{ \sqrt 2} {2}-1* \frac{ \sqrt 2} {2}

You should get:
- \frac{ \sqrt 2} {2}
