The interior angles of a triangle have measures 90°, 48°, and x°.

what is the value of x?

enter your answer in the box.
x =

42

Step-by-step explanation:

since, sum of the interior angles of a triangle is 180°

⇒    90°+48°+x°=180°

⇒     x°=180°-90°-48°

⇒      x°=42°

⇒       x=42

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%

the monthly balance will be $75,000
