17 Geometry question: Use an algebraic equation to find the measurement of each angle that is represented in terms of X

Mathematics
1 answer:
maria [59]3 years ago

Answer:

2x + 30° = 40°

4x + 30° = 50°

Step-by-step explanation:

2x + 30° and 4x + 30° are complementary angles.

Complementary angles sum up to give 90°.

Therefore,

2x + 30° + 4x + 30° = 90°

Add like terms

6x + 60 = 90

6x = 90 - 60

6x = 30

6x/6 = 30/6

x = 5

✔️2x + 30°

Plug in the value of x

2(5) + 30

10 + 30

= 40°

✔️4x + 30°

4(5) + 30°

20 + 30

= 50°

What is the vertex of the graph of #y=x^2+3x-4#?
borishaifa [10]
To find the x value of the vertex we do:

x = \frac{-b}{2a}
if your quadratic function is in the form ax² + bx + c = y

x = \frac{-3}{2(1)}
x = \frac{-3}{2}

Now we plug this x into the equation and solve for y.

y = (\frac{-3}{2}) ^{2} + 3( \frac{-3}{2} ) + 4
y = \frac{9}{4} -  \frac{9}{2} + 4
y = \frac{9}{4} - \frac{18}{4} + 4
y = \frac{-9}{4} + 4
y = \frac{-9}{4} + \frac{16}{4}
y = \frac{7}{4}

Your vertex (if my math is correct) is at ( \frac{-3}{2},  \frac{7}{4} )

What is the value of x <br><br> A. 20<br> B. 34<br> C. 60<br> D. 69
Grace [21]

Answer:

A

Step-by-step explanation:

The given angles are vertical and thus congruent, so

3x = x + 40 ( subtract x from both sides )

2x = 40 ( divide both sides by 2 )

x = 20 → A

Mrs. Hall records the heights of 50 students in a spreadsheet. The mean height is 68 inches. After looking at the data again, sh
Vedmedyk [2.9K]
67.3 repeating. You multiply 68 times 50, subtract 82 and 86, them divide by 48. If that doesn't work, try dividing by 50. That should work.
