180-(90+48)=42
You know the triangle is a right angle therefore it’ll be 90 degrees.
And the other angle will be 48 degrees because it’s an alternative angel (z angle)

42 is the answer

Answer: 30%

Step-by-step explanation:

Given: Cupcakes have sprinkles = 15

Cupcakes didn't have sprinkles = 35

Total cupcakes = 15+35 = 50

The percentage of the cupcakes had sprinkles = $\dfrac{\text{Cupcakes have sprinkles}}{\text{Total cupcakes}}\times100$

$=\dfrac{15}{50}\times100\\\\= 30\%$

Hence, the percentage of the cupcakes had sprinkles = 30%

A bag contains 6 red marbles and 2 white marbles. A marble is selected, kept out of the bag, and then another marble is selected

Finger [1]

Answer:

11/15

Step-by-step explanation:

There are 8 marbles total. If they are being selected from twice with one missing, we could add 8 and 8 - 1 together to get the denominator for the probability.

8 + (8 - 1) = 15

We have to assume the first marble taken was red, so we will have 6 plus 6 - 1 red marbles to choose from for our numerator.

6 + (6 - 1) = 11

The probability of consecutively selecting two red marbles is 11/15.
