Answer:

b = 29

Step-by-step explanation:

C x D = A x B

15(11x - 91) = 7(2x + 10)

165x - 1365 = 14x + 70

add 1365 to both sides of the equation:

165x = 14x + 1435

subtract 14x from both sides:

151x = 1435

divide both sides by 151:

x = 9.5

b = 2(9.5) + 10 = 29

Consider the triangle. 45° 80° Find the measure of the unknown third angle.

Elina [12.6K]

Answer:

$55 \degree$

Step-by-step explanation:

Let the unknown angle be x

As the interior angles in a triangle are added up to 180°

$x + 45 + 80 = 180 \\ x + 125 = 180 \\ x = 180 - 125 \\ x = 55 \degree$

Hope this helps you.

Let me know if you have any other questions:-)
