Answer:

122°

Step-by-step explanation:

The Angle Sum Property of a triangle gives that the sum of the internal angles of a triangle is equal to 180°.

Hence,

⇒ ∠A + ∠B + ∠C = 180°

⇒ ∠A + <u>43°</u> + <u>15°</u> = 180°

⇒ ∠A + 58° = 180°

⇒ ∠A = 122°

You’ve just moved into a new home and are decorating it with furniture. You head to Target and see a dining room table for $425,

Answer:

Amount of Discount: 85, Discounted cost of item: 340

Step-by-step explanation:

You Start by dividing the main price of the item by 100

You then multiply your answer from that by however much the discount is.

We divide by 100 because there is 100 percent when you are paying full price, dividing by 100 gives you the amount that is equal to 1 percent of that price

You then multiply the answer from that by 20, this will give you 20% of the full price, this will give you a discount of 85 Dollars.

To find the Discounted price you then subtract 85 from 425 and you will have an answer of 340 dollars. Hope this helps!

I’ll mark brainliest

enyata [817]

Answer:

$\text{A. }y=1.30x+1.50$

Step-by-step explanation:

The two ringtones will cost her a total of $0.75\cdot 2=1.50$ and is a fixed amount. The relationship between the cost and number of songs only is $y=1.30x$ and therefore the answer is $\boxed{\text{A. }y=1.30x+1.50}$ . You can also directly find the answer by finding the y-intercept (in this case $1.50$ ), as no other answer choices include the term $1.50$ , so A must be the correct answer.
