ABCD is a square. <br><br><br><br> What is the measure of angle BAC?

bezimeni [28]

Angle BAC is 45 degrees. The diagonal bisects angle BAD and since all angles in a square are 90 degrees, half of 90 is 45 degrees.

Answer:

$x = 13.8$

Step-by-step explanation:

Given

See attachment for triangle

Required

Find x

To find y, we make use of the relationship between sides lengths 11 & x and angle 37

The relationship is:

$cos(37) = \frac{11}{x}$

i.e.

$cos(\theta) = \frac{Adjacent}{Hypotenuse}$

Make x the subject

$x = \frac{11}{cos(37)}$

$x = \frac{11}{0.7986}$

$x = 13.7741$

$x = 13.8$ -- approximated
