1) Δ ABC

m∠B + m∠C + m∠BAC = 180⁰

2) m∠DAB + m∠BAC = 180⁰ because m∠DAB and m∠BAC are supplementary angles.

3) m∠B + m∠C + m∠BAC = m∠DAB + m∠BAC

m∠B + m∠C = m∠DAB

32⁰ + x = 98⁰

x=98 - 32 = 66 ⁰

Answer: A. 66⁰.

Answer: Option A, 66°

Step-by-step explanation:

Here we should use two things:

1) the addition of the 3 interior angles of a triangle always is equal to 180°

2) If a line cuts anoter line, two consecutive angles always add to 180°

now, we can see that the angle DA = 98°

then the angle AC can be obtained as:

AC = 180° - 98° = 82°

Now, with two of the interior angles of the triangle, we can find the other:

a + b + c = 180°

82° + 32° + c = 180°

c = 180° - 32° - 82° = 66°

so the correct option is the option A

Answer:

P(red) = .3

P(yellow) = .3

75 cubes in the box

Step-by-step explanation:

The probability has to add to 1

Since the number of red cubes equals the number of yellow cubes the probability has to be the same

.4 + x+x = 1

.4 +2x = 1

2x = 1-.4

2x = .6

Divide by 2

x = .6/2

x = .3

P(red) = .3

P(yellow) = .3

We know that

P(blue) = .4 = number of blue cubes/ total number of cubes

                 .4 = 30/total

                  total = 30/.4

                   total = 75
