Maya designed two intersecting roads. She drew the roads so that one of the angles at the intersection was 45 degrees. What are
Citrus2011 [14]
The sum of opposite angles are equal, so two of the angles are 45°.  The sum of all angles about the intersection of two lines is 360°.  So the remaining two angles are found by:

α=(360-2*45)/2

α=135°  thus all four angles are:

45°,135°,45°,135°

Suppose a triangle has sides a, b, and c, and let theta be opposite the side of length a. If cos theta < 0, what must be true
katrin2010 [14]
If \cos \theta\ \textless \ 0, then angle \theta is obtuse and triangle with sides a, b, c is obtuse triangle.
In an arbitrary triangle can be only one obtuse angle, and the side which lies opposite to the largest angle is the largest. Then since <span>angle \theta is opposite the side of length a</span>  you can conclude that a>c and a>b.

Firdavs [7]

Answer:

6.3 feet

Step-by-step explanation:

use pythagorean theorem

a² + b² = c²

a² + 3² = 7²

a² + 9 = 49

Subtract 9 from both side

a² = 40

Take the square root of both sides

a = 6.324555320336759

Rounded

a = 6.3
