Sum of all angles in a triangle is 180°

90 + x + 50 + x + 60 = 180  | All angles add up to 180
200 + 2x = 180                    | Combine like terms
2x = - 20                              | Subtract 200
x= - 10                                 | Divide by 2

Find Angle A:
Angle A = x + 50
Angle A = -10 + 50
Angle A = 40

Answer: Angle A = 40

What is the equation of the line that passes through (-5, 7) and is parallel to the line y = 4x + 5?
Marysya12 [62]

Answer:

y=4x+27

Step-by-step explanation:

If a line is parallel, it would have the same slope, so you already have that.

Now, you need the y-intercept of the second line. You already have one point, so use that point and the slope to find the y-int. What you can do (since you know you have to go up 4 and over 1, add a 1 to the -5 until you get to zero. your y-int would be 7+20 since you've gone up 5x4)

your final answer (i think) should be y=4x+27, but I could be wrong :))

0.5 is a rational number.<br> True<br> False
velikii [3]

Answer:

true

Step-by-step explanation:

Natural numbers are numbers naturally occurring in nature like 1, 2, 3, 4, 5, 6, 7, 8, 9 . . .

Whole numbers are numbers that are whole, like 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 . . . (the only difference is that there is a 0 included)

Integers include negative and positive numbers like -3, -2, -1, 0, 1, 2, 3, 4 . . .

Rational numbers are include all of the above AND anything that can be turned into a fraction, like fractions and decimals (that have an end) like 0.625, -0.5, 1, 4, 1/4, 6/15, 4.8, etc.

So in this case, yes, 0.5 is a rational number.
