This is literally a *6TH GRADE* problem

D is also the only answer above 90 degrees 😂

I did it differently. (a+b)+a+(a-b) = 3a = 180 degrees. a = 60 degrees. a = 60 degrees = 2b. b = 30 degrees. a-b = 60-30 = 30 degrees. x = 180-30 = 150 degrees.

UK high school: 2nd order differential equations, complex numbers and Gaussian elimination

US high school: 180 degrees in a triangle

[SideOfPepper]

Algebraically, it makes sense. Visually, ain’t no way a+b 90 degrees😭

[theszthstages.]

x is has an obtuse angle, it has to be greater than 90 degrees. No math is needed since the only answer greater than 90 is D. 150 degrees.

[slaysomemore]

Since there's not a note saying 'drawing not to scale' you can infer the angle is larger than 90° making 150 the only possible answer.

“Most SAT takers get this wrong”
I have a hard time believing that

[mecaterpillar]

What I wanted to see is how in the world it is that most SAT takers get this question wrong. 1) I immediately knew how to solve it without having taken any such test or question in like 20 years and 2) once I calculated the answer and looked down at the choice I see there's only one choice that's greater than 90 degrees or anywhere close to the answer. Like the choice is D. Why would anyone get this wrong?

[sannah]

I literally studied this in the 7th grade and this is a quite long solution, the solution we learnt to problem such as these were outside angle equals inside angle and studf like that

[alphareborn]

You don’t even have to solve this using algebra, can solve in 2 seconds. X is greater than a 90 degree angle and the others are less than 90, so just pick 150 automatically.

[hi_i_exist]

simpler method:
X=obtuse angle
obtuse angles>90 degrees
d is the only option above 90 degrees so its d)150

[black.]

If a = 2b,
Assuming,
A + a+b + a-b = 180 (Sum of all triangles is 180 degrees)
Converting a into 2b

2b + 2b+b + 2b-b =180

2b+ 3b + 1b =180

6b=180

B=180 by 6

B = 30

So, x + 30 =180

So, x =180-30

Therefore, s = 150

[HereIsWisdom]

Well, you all ready know its not 50, 60, or 70!

[BRUH-lxjv]

Honestly I just saw that the first 3 choices are less than 90° which automatically eliminates them as x is clearly an obtuse angle.

[thekingofsevens]

Im pretty sure that because there is no degree markers then youd either have to assume radians or say x =5b. Mistake on the SATs part.

[beepmoo]

(also u can use exteriror angles, but this is definitely a good way)

[SgwiggleMonSquiggles]

dude what this is the easiest question ever, i hope my sat is this easy

[imjustkenough]

im about to graduate with a physics degree and i got it wrong 💀
