By law of Sines:

c / sinC = b / sinB
33 / sin145 = 7 / sinB
sinB = sin145 * 7 / 33
sinB = 0.122
B = 6.99

What is 7 plus the sum of m and -17​
olasank [31]

Answer:

m - 10

Step-by-step explanation:

7 plus = 7 +

The sum of m and -17 = m + (-17)

7 + (m + -17)

We can get rid of the parentheses

7 + m + -17

Combine like terms

7 + -17 = -10

m + -10

Get rid of the addition sign

m - 10

Prove that . 1+cot2 theta = cosec2theta​
igor_vitrenko [27]

Answer:

see explanation

Step-by-step explanation:

Using the Pythagorean identity

sin²θ + cos²θ = 1 ( divide terms by sin²θ )

\frac{sin^20}{sin^20} + \frac{cos^20}{sin^20} = \frac{1}{sin^20} , that is

1 + cot²θ = cosec²θ ← as required
