umka2103 [35]

Answer:

3 (a-2) (a-5)

Step-by-step explanation:

The first step is to find the GCF. Here, it's 3.

3(a^2-7a+10)

Then, you factor the polynomial in the parenthesis.

To find the factors, you will need to find 2 numbers that add to -7, and multiply to 10. -2 and -5 add to -7 and multiply to 10. Now, replace -7a with the factors.

a^2-2a-5a+10

This of this polynomial as 2 problems.

a^2-2a        -5a+10

Then, factor again.

a^2-2a        -5a+10

a(a-2)       -5(a-5)

Then, you keep the factors in parenthesis, and combine the numbers on the outside.

(a-2)(a-5)(a-5)

Since, there are 2 of the same factor, you only need one.

(a-2)(a-5)

BUT REMEMBER!! In the very beginning, we had a 3 that we took out, we STILL need to add that to the final answer. The <u>final answer</u> is:

3 (a-2) (a-5)

d1) 20°

Complement: 90° - 20° = 80°

Supplement: 180° - 20° = 160°

d2) 77°

Complement: 90° - 77° = 13°

Supplement: 180° - 77° = 103°

d3) 101°

Complement: doesn't have a complement.

Supplement: 180° - 101° = 79°

d4) 90°

Complement: 90° - 90° = 0°

Supplement: 180° - 90° = 90°

d5) 96°

Complement: doesn't have a complement

Supplement: 180° - 96° = 84°

d6) x

Complement: 90° - x

Supplement: 180° - x
