3 0


If you have a lot of Pythagorean triples memorized, then you'd probably know immediately, but if not, then you can use the Pythagorean Theorem to calculate each one:

A.: 7^2+9^2=49+81 which is not equal to 13^2, or 169

B.: 5^2+12^2=25+144 which is not equal to 14^2, or 196

C.: 8^2+15^2=64+225=17^2=289

D.: 9^2+12^2=81+144 which isn't equal to 14^2, or 196

Therefore, the correct answer is C.

Laws of Sine just need a way to solve this, I got kicked out of my last tutor and lost the work and can't get it back
Stels [109]

The measurement of angle A = 52 ° .

In question we need to find angle A ,

To find angle A using Law of Sines :

Law of Sine : ( a / sin A ) = ( b / sin B ) = ( c / sin C ) where a , b and c are the sides opposite to angle A , B and C resp. of a triangle .

Applying Law of Sines ,

25 / sin A = 28 / sin 62

sin A = ( 25 * sin 62 ) / 28

sin A = 0.7883

Therefore , angle A = 52 ° .

Hence , the measurement of angle A = 52 ° .

Use Pascal's triangle to find the coefficient of the third term in the expansion of (a + b)2.
Alexxandr [17]

Answer:

B

Step-by-step explanation:

(a+b)^2

using Pascal triangle

1 1

1 2 1

1 3 3 1

so the third term in the expansion of (a+b)^2

we use

1 2 1

a^2 + 2ab+b

hence the coefficient of third term is 1

option B is collect
