Answer:

x is 10.66

Step-by-step explanation:

What are complementary angles?

They are angles that up to 90

So we have Sin A and Cos B

4x + 10+ 2x + 16= 90

collect like terms

6x+ 26= 90

6x= 90-26

6x= 64

x= 64/6

x= 10.66

Hence the value of x is 10.66

Jorge wrote the following key for a scale drawing of his garden: 1 cm 2 ft Express this scale as inches to feet.
Andru [333]
We know that

the scale (cm/feet)-----------> 1/2

1 in-------------> 2.54 cm
x in---------------> 1 cm
X=1/2.54------> 0.3937 in

so
 the new scale (in/feet)------------> 0.3937 in/ 2 feet-------> 0.1969 in/feet

the answer is 
0.1969 in/feet

ale4655 [162]

Answer: 45 kilometers

Step-by-step explanation:

The equation to solve this problem is:

$165 = 1.4x + 102

The variable x represents the number of kilometers he travels.

To solve the equation:

Subtract 102 from each side-

63 = 1.4x

Next divide each side by 1.4-

45 = x

Teague needs to run 45 kilometers in order to raise $165.
