May someone explain how to do this or what the answer is ?

x=30°

Step-by-step explanation:

To find the value of x we need atleast 2 other angles, and we do we have one  70, but we need to get another angle from the info given outside the triangle,

Notice, the angle beside 100 can be found by simply subtracting 180-100

(since angles are on a straight line [Supplementary angles]

So, the angle is 80

Now, we know that the angles inside a triangle add up to 180

So basically, to find x:

70+80+x = 180

150+x = 180

x = 180-150

x=30°

Hoep this helps!

Mark brainliest if you think i helped! Would really appreciate!

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
