Step-by-step explanation:

given,

measures of 3 angles of triangle,

angle 1 = 3x

angle 2 = 2x + 15°

angle 3 = 3x + 5 °

sum of the angles should be 180°

so,

angle 1 + 2 + 3 = 180°

after inserting the values we got,

3x + 2x + 15 + 3x + 5 = 180°

→ 8x + 20 = 180°

→ 8x = 180 - 20 = 160°

→ x = 160/8 = 2

→ x = 20

therefore,

angle

1 = 3x = 3 × 20 = 60

2 = 2x + 15 = 2(20) + 15 = 55°

3 = 3x + 5 = 3(20) + 5 = 65°

as given,

their sum should be 180° so,

60 + 55 + 65 = 180°

hope this answer helps you dear....

I guess dear the measure of the angles of traingle have x in their expression!...if they have than this is the answer!

Write each of the numbers 1, 4, 9, 16, and 25 as a base raised to the second power. Explain why these numbers are sometimes call

vodka [1.7K]

First, we can raise each number to the second power by multipying it by itself. :)
1^2=1
4^2=16
9^2=81
16^2=256

These numbers are called "perfect squares" because their square roots are whole numbers, rather than decimals. For example, If you had a square with an area of 16, the side legnths of the square would be the whole (thus "perfect") number 4. For this reason, 16 (4^2) is considered a "perfect square" number. I hope that makes sense!! :)

Choose Yes or No to tell whether the expressions are equivalent. 4(5c + 3) and 9c + 7 No 10f... 10 and 2(84 - 5) No 12g + 21 and

labwork [276]

6(4j - 6)

Distributing,

6(4j) - 6(6)

24j - 36

which is not equivalent to 24 - 36j

Samantha has 412 gallons of lemonade for her daughter’s birthday party. Each gallon of lemonade contains 1.5 grams of fat. How m

olasank [31]

1/2 gallon= .75 grams
1 gallon= 1.5 grams
2 gallons = 3 grams
4 gallons = 6 grams

So

4 gallons is 6 grams
Then we add on a half which is .75 grams

6g + 0.75g = 6.75g

Hope that helps ;•)

Answer:

5.06 years or 60.75 months

Step-by-step explanation:

Compound interest formula:

$AV=PV(1+\frac{i}{n})^{n*t}\\4045=3355(1+\frac{.037}{12})^{12t}\\1.025=(1.003)^{12t}\\log1.025_{1.003}=12t\\60.75=12t\\5.062$

5.06 years or 60.75 months
