Need help with angle relationships worksheet

Mathematics
1 answer:
Ludmilka [50]1 year ago
6 0

The information about the angles shows that:

  • Complementary to 40° = 50°
  • Complementary to 67° = 23°
  • Supplementary to 80° = 100°
  • Supplementary to 65° = 115°

<h3>What are complementary angles?</h3>

It should be noted that complementary angles refers to the angles that are equal to 90°. On the other hand, supplementary angles are the angles that are equal to 180°.

The complementary to 40°:

= 90° - 40°

= 50°

The complementary to 67° will be:

= 90° - 67°

= 23°

The supplementary to 80° will be:

= 180° - 80°

= 100°

The supplementary to 65° will be:

= 180° - 65°

= 115°

SV is a midsegment of △RTU.<br> If TU=y+38 and SV=y–9, what is the value of y?
pav-90 [236]

Answer:

y = 56

Step-by-step explanation:

the midsegment SV is half the length of the side TU , that is

y - 9 = \frac{1}{2} (y + 38) ← multiply both sides by 2 to clear the fraction

2y - 18 = y + 38 ( subtract y from both sides )

y - 18 = 38 ( add 18 to both sides )

y = 56

Someone plz help me 1-1\2c=6
GarryVolchara [31]

1 - 1/2c = 6

1 -1 - 1/2c = 6 -1 (subtract 1 on both sides)

-1/2c = 5 (next do the inverse operation)

c = 5 ÷ 1/2

c = -10

to check your answer substitute the value of c in the equation;

1- 1/2c = 6

1- 1/2(-10) = 6

1 + 5 = 6

6 =6

What is the constant of variation for the quadratic variation? 0.1y = 3x2
svet-max [94.6K]

Answer:

The constant of variation for the given quadratic equation is, 30

Step-by-step explanation:

One of the form of a quadratic equation is written as:

y = kx^2     ....[1]

where k is the coefficient and for this case the constant of variation.

In order to obtain the answer for the given equation, we write the given equation to the form above.

0.1y=3x^2  or

y=(\frac{3}{0.1})x^2 or

y=30x^2

Comparing this equation with equation [1], to get the value of k;

k=30.

therefore, the  constant of variation is, 30.
