the measures of two angles of a triangle are 35 degrees and 45 degrees. what is the measure of the third angle of the triangle?

Answers

Answer 1

Answer: If it is a triangle, the total degree should be equal to 180.
So the last angle
180 - (35+45)
180 - 80
100

solve

Answers

6x + 8y = 4x + 12y
6x - 4x = 12y - 8y
2x = 4y
x = 2y

is it x=2y?
Because 6x+8y=4x+12y
=>2x+8y=12y
and 2x=4y, so x=2y

Can you solve (4x-3)/(x+2)+(15)/(x-3)

Answers

Please see the pic, I'd solved in it.

$(4x-3)/(x+2)$ + $(15)/(x-3)$ = 0
1st step: We need to have a common denominator.
So we do this:
$((4x-3)*(x-3))/((x+2)*(x-3))$ + $((15)*(x+2))/((x-3)*(x+2))$ = 0
2nd step: Distribute them
$(4x^(2)-3x-12x+9)/((x-3)(x+2))$ + $(15x+30)/((x+2)(x-3))$ = 0
3rd step: Do the rest of the equation!
We can put it on one fraction, its fine.
$(4x^2-15x+9+15x+30)/((x+2)(x-3))$ = 0
$(4x^2+39)/((x+2)(x-3))$ = 0 (-15 and 15 cancels out)
4th step: take the denominator to the other side
4x²+39 = 0 (anything × 0 = 0)
5th step: Take 39 to the other side
4x² = -39
6th step: Divide by 4 on both sides
$(4x^2)/(4)$ = $-(39)/(4)$
(4 and 4 cancels out)
x² = $-(39)/(4)$
7th step: Take the square root to keep x alone
x = $-\sqrt(39)/(4)$
It can also be written as:
x = $-( √(39) )/( √(4) )$
Final answer:
x = $-( √(39) )/(2)$

Write this equation: 8.75×10−4 in standard notation

Answers

To write in standard notation means writing the equation "normally", solving it and then writing the resulting number in its extensive form with all explicit digits. 10^-4 is 0,0001, so: 8,75x0,0001=0,000875

Solve the equation for x -x*2-10x+24=0

Answers

Answer:

x=-12 x =2

Step-by-step explanation:

-x^2-10x+24=0

Divide by -1

x^2 +10x -24 = 0

Factor

What 2 terms multiply to -24 and add to 10

12 * -2 = -24

12 -2 = 10

(x+12) ( x-2) = 0

Using the zero product property

x+12 =0 x-2 =0

x=-12 x =2

The answer is x=-12 an x=2
