QveST [7]3 years ago
8 0

Answer:

4. 73

5. 40°

Step-by-step explanation:

The sum of the angles in a triangle is 180°. The sum of angles in a linear pair is 180°.

4. 45° +62° + k° = 180°

... 107 +k = 180 . . . . . collect terms, divide by °

... k = 180 -107 = 73 . . . . . subtract 107

_____

5. ∠STR = ∠SRT = 20°

... ∠STR +∠STU = 180°

... 20° + 4x = 180°

... 4x = 160° . . . . . . . . subtract 20°

... x = 40° . . . . . . . . . . divide by the coefficient of x

Can somebody help with number 4 asap please
Mars2501 [29]

Answer:

x ≈ 41

Step-by-step explanation:

All the angles in a quadrilateral add together to equal 360°

So set up the equation:

a + b + c + d = 360°

Now fill in the values we know:

x + _ + 4x + 2x - 10 + 85 = 360

7x + 75 = 360

Now subtract both sides by 75:

7x + 75 - 75 = 360 - 75

7x = 285

Divide both sides by 7:

7x / 7 = 285 / 7

x = 40.714

Round:

x = 41

Now to check our answer, substitute 41 for x in the equation:

(41) + _ + 4(41) + 2(41) - 10 + 85

(41) + 164 + 82 - 10 + 85 = 362

The answer is close to 360, so we know it is correct

Plot the x- intercept and y- intercept. then write the intercepts as ordered pairs
puteri [66]

Answer:

x-intercept = 4

y-intercept = -1

As ordered pairs they would be ( 4, 0) and ( 0, -1)

Step-by-step explanation:

The line goes through 4 on the x line and goes through -1 on the y line.

As an ordered pair you just put the numbers in their x and y spots being ( x, y )

With 4 being on the X and -1 being on the Y it would make them ( 4, 0) and

( 0, -1).
