The correct answer is: AB = 3.11

Explanation:
Since

cos(\theta) =  \frac{base}{hypotenuse} --- (1)
\theta = 50°
base = 2

And hypotenuse = AB

Plug in the values in (1):
(1) => cos(50°) = 2/AB

=> AB = 2/0.643
=> AB = 3.11

How do I do this I’ll mark u brainliest pls ?
nataly862011 [7]

Answer:

1. is a 30 60 90 triangle so x = 30

pardon my bad handwriting for below

2.

STEP 1: subtract the angle you have from 180

STEP 2: add your x values together, if there is a non x number (such as + 10) balance it out on the other side by adding or subtracting

STEP 3: divide so that x has no coeffecient in front of it

STEP 4: substitute x values with the value you got

STEP 5: verify by adding the angles you got, it'll be correct if it equals 180
