Solve for x. Round to the nearest tenth, if necessary.
Brilliant_brown [7]

Answer:

x = 63.9

Step-by-step explanation:

We have:

\frac{QR}{sin35} = \frac{78}{sin90}

=> QR × sin90 = 78 × sin35

=> QR × sin90 = 44.7

=> QR = 44.7

But, we also have: x^{2} + QR^{2} = 78^{2} <=> x^{2} + 44.7^{2} = 78^{2} <=> x^{2} = 6084 - 1998.09

=> x^{2} = 4085.91

=> x = \sqrt{4085.91} = 63.9211.. = 63.9

You leave home and walk 3 blocks east, then 4 blocks north. How far are you from<br><br>home?
lara31 [8.8K]
I believe the answer would 5 blocks

If you go 3 blocks East and 4 north, they are like the straight sides of a triangle, so to find the diagonal distance, or the shortest distance, you would find the diagonal side of a triangle it is
A squared + B squared = C squared

So 3x3 = 9
And 4x4 = 16
16+9=25
And the square root of 25 is 5

Please correct me if I am wrong and have a good day
