In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the third is 92° more tha
lesya692 [45]

Answer:

The measure of first angle is 44°.

The measure of second angle is 22°.

The measure of third angle is 114°.

Step-by-step explanation:

First, you have to form expressions for the 3 angles. Let second angle be x :

First angle = (2x)°

Second angle = x°

Third angle = (92 + x)°

Next, you have to add up altogether as the total angles in a triangle is 180° :

2x + x + 92 + x = 180

4x + 92 = 180

4x = 180 - 92

4x = 88

x = 88 ÷ 4

x = 22°

Lastly, you have to substitute the x-value into the expressions :

First angle = 2(22) = 44°

Second angle = 22°

Third angle = 92 + 22 = 114°

So we’re doing these segment ratios things in my math period and I need help on problem two thank you!! :3
iragen [17]

Answer:


Step-by-step explanation:

There could be 2 3 4 6 or 12. You can use any number that divides evenly into 12. I don't think you can use 1 because the question says members. The next question is, do you include Sharon in the group (so she gives herself a share) and again I will answer yes. She has to get something out of the deal.

2: each member gets 3 red and 3 white. ( don't say 6 red and 6 white.)

3: Each member gets 4 in total 2 red and 2 white each

4: Each member gets 4 in total. This can be split 2 ways.

6: Each member gets 2 in total: 1 red and 1 white.

12: Each member gets 1. 6 get red and the others get white.
