Answer:

<1 = 55 degrees and <2 = 35 degrees

Step-by-step explanation:

Sum of complementary angles is 90.

<1 = 3x + 10

<2 = 4x - 25

3x + 10 + 4x - 25 = 90

7x - 15 = 90

7x = 105

x = 15

<1 = 3(15) + 10

<1 = 55

<2 = 4(15) - 25

<2 = 35

Answer:

Dive by n square root two, also option one.

Step-by-step explanation:

The first step to any algebra equation is to isolate the variable and you do that by divide square root 2 since it cancels out on the left side and now n is alone.

Hoped that helped :)

How do I factor the equation in writing this question?

SCORPION-xisa [38]

Step-by-step explanation:

You are just replacing the 'n' with the number in the 'n box'.

So if this is the formula:

$b(n) = 4 - (n \div 3)$

then:

B(-3)= 4-(-3/3)

B(-3)= 4-( -1)

B(-3)= 4+1

B(-3)= 5

B(0)= 4-(0/3)

B(0)= 4-0

B(0)= 4

B(3)= 4-(3/3)

B(3)= 4-1

B(3)= 3
