Which set of angle measures could be the interior angles of a triangle?

andriy [413]

Answer:

d. 15, 30, 135

Step-by-step explanation:

A triangle's interior angles on a flat surface add up to 180 degrees.

a. 90 * 3 = 270 != 180

b.(80 * 2) + 200 = 360 != 180

c.40 + 50 + 60 = 160 != 180

d.15 + 30 + 135 = 45 + 135 = 180, so it has to be d.

Answer: $\textsf{x = - 1 / 3}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{3x + 1}$

Find: $\textsf{The value of the unknown variable x}$

Solution: In order to solve for x we need to isolate it with the first step being to subtract 1 from both sides and then we would divide both sides by 3 to give us the solution.

<u>Subtract 1 from both sides</u>

$\textsf{3x + 1 = 0}$

$\textsf{3x + 1 - 1 = 0 - 1}$

$\textsf{3x = 0 - 1}$

$\textsf{3x = - 1}$

<u>Divide both sides by 3</u>

$\textsf{3x / 3 = - 1 / 3}$

$\textsf{x = - 1 / 3}$

Therefore, the final answer would be that x is equal to -1/3.

JulsSmile [24]

1) 3j + 5p = 7.60 and 1j + 2p = 2.90

2) Solving for j and p
j = 2.90 - 2p

3(2.90 - 2p) + 5p = 7.60
8.7 - 6p + 5p = 7.60
8.7 - p = 7.60
-p = -1.1
p = 1.1

1j + 2(1.1) = 2.9
j + 2.2 = 2.9
j = .7

3) The values of p and q:
p = $1.1 per pancake, j = .70 cents per glass
