The people she's asking are on a winter weekend so they've most likely been skiing. She should've asked random people for a more fair percentage.

Triangle ABC is shown the measure of the interior angle at point A is 40 and the exterior angle point C is 102

mixas84 [53]

Answer:

∠C (Interior) =78°

∠B (Interior) = 62°

Step-by-step explanation:

Given:

∠A (Interior) = 40°

∠C (exterior) = 102°

Computation:

∠C (Interior) = 180° - 102°

∠C (Interior) =78°

∠B (Interior) = 180° - ∠A (Interior) - ∠C (Interior)

∠B (Interior) = 180° - 78° - 40°

∠B (Interior) = 180° - 118°

∠B (Interior) = 62°

-6(x+7)=-4x-2<br> How many solutions does it have

geniusboy [140]

Answer:

Equation have Unique solution i.e $x=-20$

Step-by-step explanation:

Given Equation:

$-6(x+7)=-4x-2$

Solving the Equation for 'x'.

$-6(x)-6(7)=-4x-2\\\\-6x-42=-4x-2$

Adding ' $4x$ ' both sides:

$-6x+4x-42=-4x+4x-2\\\\-6x+4x-42=-2\\\\-2x-42=-2$

Adding '42' both sides:

$-2x-42+42=-2+42\\\\-2x=40$

$x=\frac{40}{-2} \\\\x=-20$

The equation have Unique solution with the value of $x=-20$
