Please help me ! not sure what to do. i also need to show steps

70 degrees

Step-by-step explanation:

The exterior angle in a triangle is equal to the sum of the two opposite interior angles

So,

the two interior angles in the question are U and T while the exterior angle is V.

Using this,

U+T =V

U+50 = 120

(make U the subject of formula)

U = 120 - 50

U = 70 degrees

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
