ΔABC is a right triangle. m ∠A is 6° less than three times m ∠B.

Mathematics
1 answer:
Marta_Voda [28]3 years ago
6 0
M∠A = 3x - 6
m∠B = x

180° = 90° + (3x - 6°) + x
4x - 6° = 180° - 90°
4x = 96°
x = 24°

m∠A = 3(24°) - 6°
m∠A = 66°
m∠B = 24°

Inqualities question pls help!
Margaret [11]

Answer:

B

Step-by-step explanation:

The closed circle at - \frac{3}{2} indicates that x can equal this value

The open circle at \frac{7}{2} indicates that x cannot equal this value.

All values of x between - \frac{3}{2} and \frac{7}{2} are valid, thus

- \frac{3}{2} ≤ x < \frac{7}{2} → B

A box contains 8 red markers, 5 green markers, and 5 blue markers. Once a marker is pulled from the box, it is replaced, and the
Andru [333]

Well. add all of these up 8+5+5. we know 5+5 is 10. and 10+8 is 18. so 18 is the denominator.  There are 8 red markers and 5 blue markers at 8 and 5 up. 8+5 is 13 right? So the numerator will be 13.  but the probability of picking a blue then a red is 13 alone or if you are ask for out of the amount of markers there are, its 13/18. so the probability is 13 or 13/18.
