Answer:
x = 15
Step-by-step explanation:
<u>Given</u>:
∠1 + ∠2 = 90°
∠1 = 45°
∠2 = 3x°
<u>Find</u>:
x
<u>Solution</u>:
Using the given values in the given equation, we have ...
45° +3x° = 90°
15 + x = 30 . . . . . . divide by 3°
x = 15 . . . . . . . . . . . subtract 15
Answer:
alright so you got 2 points! now this is the slope formula! y2-y1/x2-x1
okay let's label your points! (x1 0,y1 -3) (x2 2,y2 1)
let's follow the formula this makes it so we can solve! 1--3/2-0
I understand you may get a decimal but don't use 2.5 use a fraction because teachers seem to like fractions and general decimals can be hard to use (experience lol) 2.5 is 5/2 so this means your slope is 5/2
this formula works every single time and if you memorize it you can do any other problems with 2 points! please memorize y2-y1/x2-x1
2,300,000 + 510,000 = 2,810,000 them move a decimal to where is greater then 1
2.81 x 10^6 but wait, there isnt an answer for this so it has to be 28.1 x 10^5 witch is B
You know that the sum of the interior angles in a triangle is 180
we will add all the angles,
(x+8)+(2x-8)+(3x-12)=180
x+8+2x-8+3x-12=180 8 and -8 cancel out
6x-12=180
6x=180+12
6x=192
x=192/6=32
x=32
