Answer: 0.5049
Step-by-step explanation:
The probability that the first card drawn is a heart is 13/52 = 1/4
The probability that the second card drawn, without replacement, is a spade is 13/51
So the probability of drawing a heart for the first card and spade for the second card is
1/4 + 13/51 = 103 / 204 = 0 5049

Step-by-step explanation:
Answer:
3x-120 = x - 30
2x -120 = -30
2x= 90
x= 45
3(45) -120 (plug x into angle p to check your answer)
135-120
15 degrees
45-30 (plug x into angle r to make sure it's the same thing as angle p)
15 degrees (they're equal so now figure out angle Q and answer the question)
180 - (15 +15)
180- 30
150 is the measure of angle Q
so, the triangle is an obtuse isosceles triangle
