One angle of a triangle measures 136º. The other two angles are congruent.

WINSTONCH [101]

Answer:

22°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + x + 136° = 180°

2x + 136° = 180° ( subtract 136° from both sides )

2x = 44° ( divide both sides by 2 )

x = 22°

Find all possible values for A, B and C

Aliun [14]

The sum of A and B can have no carry. If we assume A ≠ B ≠ C, then you can have ...

... (A, B, C) ∈ {(1, 2, 3), (2, 1, 3), (1, 3, 4), (3, 1, 4), (1, 4, 5), (4, 1, 5), (1, 5, 6), (5, 1, 6), (1, 6, 7), (6, 1, 7), (1, 7, 8), (7, 1, 8), (1, 8, 9), (8, 1, 9), (2, 3, 5), (3, 2, 5), (2, 4, 6), (4, 2, 6), (2, 5, 7), (5, 2, 7), (2, 6, 8), (6, 2, 8), (2, 7, 9), (7, 2, 9), (3, 4, 7), (4, 3, 7), (3, 5, 8), (5, 3, 8), (3, 6, 9), (6, 3, 9), (4, 5, 9), (5, 4, 9)}

What is the following profuct?<br><br> ( sqrt 14 - sqrt 3) ( sqrt 12 + sqrt 7)

GalinKa [24]

Using the distributive law:-

this = sqrt 14 sqrt 12 + sqrt 14 sqrt 7 - sqrt 3 sqrt 12 - sqrt 3 sqrt 7

= sqrt1 68 + sqrt 91 - sqrt 36 - sqrt 21

= sqrt 168 + sqrt 91 - sqrt21 - 6

Solve: 2x2-x = 21 {-7/2,3} {-3, 7/2}

Sergio039 [100]

Answer:

The answer is (-3,7/2)

Step-by-step explanation:

$2 {x}^{2} - x - 21 = 0 \\ (2x - 7)(x + 3) = 0 \\ 2x - 7 = 0 \: \: \: or \: \: x + 3 = 0 \\ x = \frac{7}{2} \: \: and \: x = - 3$
