I need help finding the area of these two​

Mathematics
1 answer:
S_A_V [24]3 years ago
6 0

Answer:

50 cm² and 56 cm²

Step-by-step explanation:

The area (A) is calculated as

A = \frac{1}{2} × d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )

(2)

A = \frac{1}{2} × (8 + 2) × (5 + 5)

   = 0.5 × 10 × 10

   = 5 × 10

    = 50 cm²

(3)

A = \frac{1}{2} × (12 + 2) × (4 + 4)

   = 0.5 × 14 × 8

   = 7 × 8

    = 56 cm²

Find the measure of a positive angle and a negative angle that are coterminal with 100° sketch of three angles labeling clearly
docker41 [41]

Coterminal angles are different angles that have the same terminal side.

A positive angle has one turn more around so it has a measure of 100°+360° = 460°.

A negative angle will have a measure that is represented in clockwise rotation and be equal to 100° - 360° = -260°.

We can sketch an angle of measure 100°, a positive coterminal angle and a negative coterminal angle as:

Serhud [2]

Answer:

SF = 7/3

Step-by-step explanation:

Like the problem hint says, you want to put the new coordinate over the old one to find the scale factor. We'll use both x and y.

-7/-3 = 7/3

14/6 = 7/3

Therefore, the scale factor is 7/3.

Write an equation parallel to y= -5/2x + 9 that passes through the point (-6,7) brainly
frozen [14]

Answer:

Step-by-step explanation:

If two lines are parallel, that means their slopes are equal.

And we also know that the line must pass through (-6,7)

And with our point-slope equation, we get the equation:

y-7 = -\frac{5}{2} (x+6)

y - 7 = -\frac{5}{2} x-15\\y= -\frac{5}{2} x-8<------ Answer

Hope that helps!
