<u>Answer:</u>
The value of cos 45 degrees in simplified radical form is 0.70710 approximately.
<u>Solution:</u>
Given, Cos of angle 45 degrees.
We have to find the value of the Cos of 45 degrees in radical form.
From trigonometric ratios,
Cos of angle 45 degrees = cos 45 = 
Multiplying numerator and denominator with square root of 2

The value of square root of 2 is 1.414213

Hence, the value of Cos of angle 45 degrees is 0.70710 approximately
Answer:
x = 4, x = - 8
Step-by-step explanation:
(x+ 2)² = 36
√(x+2)² = + √36 √(x+2)² = -√36
x+2 = 6 x+2 = -6
x= 4 x = - 8
The solution is where the two lines meet. From the the graph, it looks like
(1, -1)
Answer:
ED = 8
Step-by-step explanation:
2x+4 = (3/2)x+6
2x = (3/2)x+2
(1/2)x = 2
x = 4
ED = 4+4 = 8
