A triangle's measures are in the extended ratio of 2:4:9 find the measures of angles

Mathematics
1 answer:
Margaret [11]2 years ago

Answer:

24°:48°:108°

Step-by-step explanation:

Since the sum of angles in a triangle is 180°, we can do 180÷15 to find the degree for 1 in the ratio. 180÷15 = 12.

12°×2 = 24°

12°×4 = 48°

12°×9 = 108°

The ratio is 24°:48°:108°

I need help so someone plz give me the steps and answer and graph it so i can understand how to solve these types of problems ag
Eddi Din [679]
Y + 6 = 4/5( x + 3)
y + 6 = 4/5x + (3(4))/5

y + 6 = 4/5x + (12)/5
y + 6 = 4/5x + 12/5
y + 6 (-6) = 4/5x + 12/5 (-6)
y = 4/5x + 12/5 (- 30/5)


y = 4/5x - 3.6 ( y = mx + b formula)

4/5 = 0.8

y = 0.8x - 3.6

x = 1
y = 0.8(1) - 3.6
y = - 2.8

x = 2
y = 0.8(2) - 3.6
y = 1.6 - 3.6
y = -2

x = 3
y = 0.8(3) - 3.6
y = 2.4 - 3.6
y = - 1.2

x = 4
y = 0.8(4) - 3.6
y = 3.2 - 3.6
y =  - 0.4

x = 5
y = 0.8(5) - 3.6
y = 4 - 3.6
y = 0.4

etc.

graph  using the (x,y)

connect the dots

hope this helps

Tashia ate 1/3 of a pizza, and Jay ate 3/8 of the same pizza. What fraction of the pizza was eaten?
Sauron [17]
This is basically saying how much of the pizza did Tashia and Jay both ate, thus combining their portions together.

1/3 + 3/8 = fraction of pizza eaten

To add fractions, you must have a common denominator. Which is 24 in this case because 3*8 = 24.

So you multiply 1/3 with 8 and multiply 3/8 with 3.

1/3*8= 8/24
3/8*3= 9/24

Now you add the fractions.
8/24+9/24= 17/24. You add the numerator, the denominator stays the same.

17/24 of the pizza was eaten.

(2x^3+6x-1)+(3x^2-7x)
sattari [20]

For this case we must simplify the following expression:

(2x ^ 3 + 6x-1) + (3x ^ 2-7x)

We eliminate the parentheses taking into account that:

+ * + = +\\+ * - = -

So, we have:

2x ^ 3 + 6x-1 + 3x ^ 2-7x =

We add similar terms taking into account that:

Different signs are subtracted and the sign of the major is placed:

2x ^ 3 + 3x^2-x-1

Answer:

2x ^ 3 + 3x^2-x-1
