It's D! This is because all of the angles add up to 180 degrees.
The answer is NOT A, because 90+90+90 is 270, which is greater than 180, so not a triangle.

Answer:

-0.5, 2, 4.5, 7, 9.5

Step-by-step explanation:

The given terms are 6 apart, so the common difference is 1/6 of their difference:

d = (12 -(-3))/6 = 15/6 = 5/2 = 2.5

Add 2.5 to each term to get the next one. Then the sequence is ...

-3, -0.5, 2.0, 4.5, 7.0, 9.5, 12

In 10 years, a child’s age will be 6 years less than triple her current age. Find the child’s current age.

Pavel [41]

Answer:

Her current age is 8 years old.

Step-by-step explanation:

Current age: x

"In 10 years, a child’s age will be 6 years less than triple her current age."

In 10 years: x + 10

6 years less than triple: 3x - 6

x + 10 = 3x - 6

solve.

16 = 2x

x = 8
