Alright, lets say the measure of the 3rd angle (the smallest one) is x degree, then measure of the 1st angle will be (x + 25) degree, and 2nd one: 3x degree. The sum of all the angles in any triangles is 180 degrees.

(x + 25) + 3x + x = 180

5x + 25 = 180 ---> 5x = 180 - 25 ---> 5x = 155 ---> x = 155/5 ---> x = 31o (third angle)

31 + 25 = 56o (first angle)

3 × 31 = 93o (second angle)

56 + 93 + 31 = 180

What’s the correct answer

laila [671]

C. 502

All you need to do is multiply the number if sales by the percentage in decimal form. Using DPR I know that 11% is equal to 0.11, so 4,560(0.11) is 501.60. That can be rounded to 502 sales that were shirts.

How do i solve x squared = 4x -5

ICE Princess25 [194]

Answer:

x = 2 ±i

Step-by-step explanation:

x^2 = 4x-5

Subtract 4x from each side

x^2 - 4x = 4x-5 -4x

x^2 - 4x= -5

Complete the square

Take the coefficient of the x term, divide by 2 and square it

-4/2 =2 2^2 =4

Add 4 to each side

x^2 -4x+4 = -5 +4

The left side is (x-coefficient of the x term/2)^2

(x-2)^2 = -1

Take the square root of each side

sqrt((x-2)^2) = sqrt(-1)

x-2 = ±i

Add 2 to each side

x-2+2 = 2 ±i

x = 2 ±i

Find a polynomial function p of lowest degree, having rational coefficients, with the given zero. 5i

weqwewe [10]

If we have one zero of +5i, we also have to have its conjugate which is -5i. Therefore, the factors that we will FOIL to get that polynomial are (x+5i)(x-5i). That distribution results in $x^{2} -25 i^{2}$ . I'm sure by now you know that i squared is equal to -1, so -25(-1) = 25. So our polynomial is $x^{2} +25=y$

Eliza is two years younger than half her bro Juan age write an equation to represent Eliza’s age ; if Juan is 6 how old is Eliza

cricket20 [7]

Answer:

Eliza is 1

Step-by-step explanation:

If Eliza is 2 years younger than 1/2 her brothers age and Juan is 6.

- divide 6 by 2 (6÷2=3)

- Take 3 away from 2 ( 3-2=1)

So that means Eliza would be 1
